+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+https://www.intel.com/support
+
+
+Command Line Parameters
+=======================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+    modprobe e1000e [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+    modprobe e1000e InterruptThrottleRate=16000,16000
+
+In this case, there are two network ports supported by e1000e in the system.
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+InterruptThrottleRate
+---------------------
+:Valid Range: 0,1,3,4,100-100000
+:Default Value: 3
+
+Interrupt Throttle Rate controls the number of interrupts each interrupt
+vector can generate per second. Increasing ITR lowers latency at the cost of
+increased CPU utilization, though it may help throughput in some circumstances.
+
+Setting InterruptThrottleRate to a value greater or equal to 100
+will program the adapter to send out a maximum of that many interrupts
+per second, even if more packets have come in. This reduces interrupt
+load on the system and can lower CPU utilization under heavy load,
+but will increase latency as packets are not processed as quickly.
+
+The default behaviour of the driver previously assumed a static
+InterruptThrottleRate value of 8000, providing a good fallback value for
+all traffic types, but lacking in small packet performance and latency.
+The hardware can handle many more small packets per second however, and
+for this reason an adaptive interrupt moderation algorithm was implemented.
+
+The driver has two adaptive modes (setting 1 or 3) in which
+it dynamically adjusts the InterruptThrottleRate value based on the traffic
+that it receives. After determining the type of incoming traffic in the last
+timeframe, it will adjust the InterruptThrottleRate to an appropriate value
+for that traffic.
+
+The algorithm classifies the incoming traffic every interval into
+classes.  Once the class is determined, the InterruptThrottleRate value is
+adjusted to suit that traffic type the best. There are three classes defined:
+"Bulk traffic", for large amounts of packets of normal size; "Low latency",
+for small amounts of traffic and/or a significant percentage of small
+packets; and "Lowest latency", for almost completely small packets or
+minimal traffic.
+
+ - 0: Off
+      Turns off any interrupt moderation and may improve small packet latency.
+      However, this is generally not suitable for bulk throughput traffic due
+      to the increased CPU utilization of the higher interrupt rate.
+ - 1: Dynamic mode
+      This mode attempts to moderate interrupts per vector while maintaining
+      very low latency. This can sometimes cause extra CPU utilization. If
+      planning on deploying e1000e in a latency sensitive environment, this
+      parameter should be considered.
+ - 3: Dynamic Conservative mode (default)
+      In dynamic conservative mode, the InterruptThrottleRate value is set to
+      4000 for traffic that falls in class "Bulk traffic". If traffic falls in
+      the "Low latency" or "Lowest latency" class, the InterruptThrottleRate is
+      increased stepwise to 20000. This default mode is suitable for most
+      applications.
+ - 4: Simplified Balancing mode
+      In simplified mode the interrupt rate is based on the ratio of TX and
+      RX traffic.  If the bytes per second rate is approximately equal, the
+      interrupt rate will drop as low as 2000 interrupts per second.  If the
+      traffic is mostly transmit or mostly receive, the interrupt rate could
+      be as high as 8000.
+ - 100-100000:
+      Setting InterruptThrottleRate to a value greater or equal to 100
+      will program the adapter to send at most that many interrupts per second,
+      even if more packets have come in. This reduces interrupt load on the
+      system and can lower CPU utilization under heavy load, but will increase
+      latency as packets are not processed as quickly.
+
+NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
+RxAbsIntDelay parameters. In other words, minimizing the receive and/or
+transmit absolute delays does not force the controller to generate more
+interrupts than what the Interrupt Throttle Rate allows.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 0
+
+This value delays the generation of receive interrupts in units of 1.024
+microseconds. Receive interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. Increasing this value adds extra
+latency to frame reception and can end up decreasing the throughput of TCP
+traffic. If the system is reporting dropped receives, this value may be set
+too high, causing the driver to run out of available receive descriptors.
+
+CAUTION: When setting RxIntDelay to a value other than 0, adapters may hang
+(stop transmitting) under certain network conditions. If this occurs a NETDEV
+WATCHDOG message is logged in the system event log. In addition, the
+controller is automatically reset, restoring the network connection. To
+eliminate the potential for the hang ensure that RxIntDelay is set to 0.
+
+RxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+receive interrupt is generated. This value ensures that an interrupt is
+generated after the initial packet is received within the set amount of time,
+which is useful only if RxIntDelay is non-zero. Proper tuning, along with
+RxIntDelay, may improve traffic throughput in specific network conditions.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 8
+
+This value delays the generation of transmit interrupts in units of 1.024
+microseconds. Transmit interrupt reduction can improve CPU efficiency if
+properly tuned for specific network traffic. If the system is reporting
+dropped transmits, this value may be set too high causing the driver to run
+out of available transmit descriptors.
+
+TxAbsIntDelay
+-------------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+This value, in units of 1.024 microseconds, limits the delay in which a
+transmit interrupt is generated. It is useful only if TxIntDelay is non-zero.
+It ensures that an interrupt is generated after the initial Packet is sent on
+the wire within the set amount of time. Proper tuning, along with TxIntDelay,
+may improve traffic throughput in specific network conditions.
+
+copybreak
+---------
+:Valid Range: 0-xxxxxxx (0=off)
+:Default Value: 256
+
+The driver copies all packets below or equaling this size to a fresh receive
+buffer before handing it up the stack.
+This parameter differs from other parameters because it is a single (not 1,1,1
+etc.) parameter applied to all driver instances and it is also available
+during runtime at /sys/module/e1000e/parameters/copybreak.
+
+To use copybreak, type::
+
+    modprobe e1000e.ko copybreak=128
+
+SmartPowerDownEnable
+--------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+Allows the PHY to turn off in lower power states. The user can turn off this
+parameter in supported chipsets.
+
+KumeranLockLoss
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+This workaround skips resetting the PHY at shutdown for the initial silicon
+releases of ICH8 systems.
+
+IntMode
+-------
+:Valid Range: 0-2
+:Default Value: 0
+
+   +-------+----------------+
+   | Value | Interrupt Mode |
+   +=======+================+
+   |   0   |     Legacy     |
+   +-------+----------------+
+   |   1   |       MSI      |
+   +-------+----------------+
+   |   2   |      MSI-X     |
+   +-------+----------------+
+
+IntMode allows load time control over the type of interrupt registered for by
+the driver. MSI-X is required for multiple queue support, and some kernels and
+combinations of kernel .config options will force a lower level of interrupt
+support.
+
+This command will show different values for each type of interrupt::
+
+  cat /proc/interrupts
+
+CrcStripping
+------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+Strip the CRC from received packets before sending up the network stack. If
+you have a machine with a BMC enabled but cannot receive IPMI traffic after
+loading or enabling the driver, try disabling this feature.
+
+WriteProtectNVM
+---------------
+:Valid Range: 0,1
+:Default Value: 1 (enabled)
+
+If set to 1, configure the hardware to ignore all write/erase cycles to the
+GbE region in the ICHx NVM (in order to prevent accidental corruption of the
+NVM). This feature can be disabled by setting the parameter to 0 during initial
+driver load.
+
+NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
+via setting the parameter to zero. Once the NVM has been locked (via the
+parameter at 1 when the driver loads) it cannot be unlocked except via power
+cycle.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 8996. This value coincides
+with the maximum Jumbo Frames size of 9018 bytes.
+
+NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+poor performance or loss of link.
+
+NOTE: The following adapters limit Jumbo Frames sized packets to a maximum of
+4088 bytes:
+
+  - Intel(R) 82578DM Gigabit Network Connection
+  - Intel(R) 82577LM Gigabit Network Connection
+
+The following adapters do not support Jumbo Frames:
+
+  - Intel(R) PRO/1000 Gigabit Server Adapter
+  - Intel(R) PRO/1000 PM Network Connection
+  - Intel(R) 82562G 10/100 Network Connection
+  - Intel(R) 82562G-2 10/100 Network Connection
+  - Intel(R) 82562GT 10/100 Network Connection
+  - Intel(R) 82562GT-2 10/100 Network Connection
+  - Intel(R) 82562V 10/100 Network Connection
+  - Intel(R) 82562V-2 10/100 Network Connection
+  - Intel(R) 82566DC Gigabit Network Connection
+  - Intel(R) 82566DC-2 Gigabit Network Connection
+  - Intel(R) 82566DM Gigabit Network Connection
+  - Intel(R) 82566MC Gigabit Network Connection
+  - Intel(R) 82566MM Gigabit Network Connection
+  - Intel(R) 82567V-3 Gigabit Network Connection
+  - Intel(R) 82577LC Gigabit Network Connection
+  - Intel(R) 82578DC Gigabit Network Connection
+
+NOTE: Jumbo Frames cannot be configured on an 82579-based Network device if
+MACSec is enabled on the system.
+
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE: When validating enable/disable tests on some parts (for example, 82578),
+it is necessary to add a few seconds between tests when working with ethtool.
+
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool* utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+
+Enabling Wake on LAN* (WoL)
+---------------------------
+WoL is configured through the ethtool* utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the e1000e driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A for the following devices:
+- Intel(R) PRO/1000 PT Dual Port Network Connection
+- Intel(R) PRO/1000 PT Dual Port Server Connection
+- Intel(R) PRO/1000 PT Dual Port Server Adapter
+- Intel(R) PRO/1000 PF Dual Port Server Adapter
+- Intel(R) PRO/1000 PT Quad Port Server Adapter
+- Intel(R) Gigabit PT Quad Port Server ExpressModule

-Identifying Your Adapter
-========================
-For information on how to identify your adapter, and for the latest Intel
-network drivers, refer to the Intel Support website:
-https://www.intel.com/support
-
-
-Command Line Parameters
-=======================
-If the driver is built as a module, the following optional parameters are used
-by entering them on the command line with the modprobe command using this
-syntax::
-
-    modprobe e1000e [<option>=<VAL1>,<VAL2>,...]
-
-There needs to be a <VAL#> for each network port in the system supported by
-this driver. The values will be applied to each instance, in function order.
-For example::
-
-    modprobe e1000e InterruptThrottleRate=16000,16000
-
-In this case, there are two network ports supported by e1000e in the system.
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-NOTE: A descriptor describes a data buffer and attributes related to the data
-buffer. This information is accessed by the hardware.
-
-InterruptThrottleRate
----------------------
-:Valid Range: 0,1,3,4,100-100000
-:Default Value: 3
-
-Interrupt Throttle Rate controls the number of interrupts each interrupt
-vector can generate per second. Increasing ITR lowers latency at the cost of
-increased CPU utilization, though it may help throughput in some circumstances.
-
-Setting InterruptThrottleRate to a value greater or equal to 100
-will program the adapter to send out a maximum of that many interrupts
-per second, even if more packets have come in. This reduces interrupt
-load on the system and can lower CPU utilization under heavy load,
-but will increase latency as packets are not processed as quickly.
-
-The default behaviour of the driver previously assumed a static
-InterruptThrottleRate value of 8000, providing a good fallback value for
-all traffic types, but lacking in small packet performance and latency.
-The hardware can handle many more small packets per second however, and
-for this reason an adaptive interrupt moderation algorithm was implemented.
-
-The driver has two adaptive modes (setting 1 or 3) in which
-it dynamically adjusts the InterruptThrottleRate value based on the traffic
-that it receives. After determining the type of incoming traffic in the last
-timeframe, it will adjust the InterruptThrottleRate to an appropriate value
-for that traffic.
-
-The algorithm classifies the incoming traffic every interval into
-classes.  Once the class is determined, the InterruptThrottleRate value is
-adjusted to suit that traffic type the best. There are three classes defined:
-"Bulk traffic", for large amounts of packets of normal size; "Low latency",
-for small amounts of traffic and/or a significant percentage of small
-packets; and "Lowest latency", for almost completely small packets or
-minimal traffic.
-
- - 0: Off
-      Turns off any interrupt moderation and may improve small packet latency.
-      However, this is generally not suitable for bulk throughput traffic due
-      to the increased CPU utilization of the higher interrupt rate.
- - 1: Dynamic mode
-      This mode attempts to moderate interrupts per vector while maintaining
-      very low latency. This can sometimes cause extra CPU utilization. If
-      planning on deploying e1000e in a latency sensitive environment, this
-      parameter should be considered.
- - 3: Dynamic Conservative mode (default)
-      In dynamic conservative mode, the InterruptThrottleRate value is set to
-      4000 for traffic that falls in class "Bulk traffic". If traffic falls in
-      the "Low latency" or "Lowest latency" class, the InterruptThrottleRate is
-      increased stepwise to 20000. This default mode is suitable for most
-      applications.
- - 4: Simplified Balancing mode
-      In simplified mode the interrupt rate is based on the ratio of TX and
-      RX traffic.  If the bytes per second rate is approximately equal, the
-      interrupt rate will drop as low as 2000 interrupts per second.  If the
-      traffic is mostly transmit or mostly receive, the interrupt rate could
-      be as high as 8000.
- - 100-100000:
-      Setting InterruptThrottleRate to a value greater or equal to 100
-      will program the adapter to send at most that many interrupts per second,
-      even if more packets have come in. This reduces interrupt load on the
-      system and can lower CPU utilization under heavy load, but will increase
-      latency as packets are not processed as quickly.
-
-NOTE: InterruptThrottleRate takes precedence over the TxAbsIntDelay and
-RxAbsIntDelay parameters. In other words, minimizing the receive and/or
-transmit absolute delays does not force the controller to generate more
-interrupts than what the Interrupt Throttle Rate allows.
-
-RxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 0
-
-This value delays the generation of receive interrupts in units of 1.024
-microseconds. Receive interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic. Increasing this value adds extra
-latency to frame reception and can end up decreasing the throughput of TCP
-traffic. If the system is reporting dropped receives, this value may be set
-too high, causing the driver to run out of available receive descriptors.
-
-CAUTION: When setting RxIntDelay to a value other than 0, adapters may hang
-(stop transmitting) under certain network conditions. If this occurs a NETDEV
-WATCHDOG message is logged in the system event log. In addition, the
-controller is automatically reset, restoring the network connection. To
-eliminate the potential for the hang ensure that RxIntDelay is set to 0.
-
-RxAbsIntDelay
--------------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 8
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-receive interrupt is generated. This value ensures that an interrupt is
-generated after the initial packet is received within the set amount of time,
-which is useful only if RxIntDelay is non-zero. Proper tuning, along with
-RxIntDelay, may improve traffic throughput in specific network conditions.
-
-TxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 8
-
-This value delays the generation of transmit interrupts in units of 1.024
-microseconds. Transmit interrupt reduction can improve CPU efficiency if
-properly tuned for specific network traffic. If the system is reporting
-dropped transmits, this value may be set too high causing the driver to run
-out of available transmit descriptors.
-
-TxAbsIntDelay
--------------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 32
-
-This value, in units of 1.024 microseconds, limits the delay in which a
-transmit interrupt is generated. It is useful only if TxIntDelay is non-zero.
-It ensures that an interrupt is generated after the initial Packet is sent on
-the wire within the set amount of time. Proper tuning, along with TxIntDelay,
-may improve traffic throughput in specific network conditions.
-
-copybreak
----------
-:Valid Range: 0-xxxxxxx (0=off)
-:Default Value: 256
-
-The driver copies all packets below or equaling this size to a fresh receive
-buffer before handing it up the stack.
-This parameter differs from other parameters because it is a single (not 1,1,1
-etc.) parameter applied to all driver instances and it is also available
-during runtime at /sys/module/e1000e/parameters/copybreak.
-
-To use copybreak, type::
-
-    modprobe e1000e.ko copybreak=128
-
-SmartPowerDownEnable
---------------------
-:Valid Range: 0,1
-:Default Value: 0 (disabled)
-
-Allows the PHY to turn off in lower power states. The user can turn off this
-parameter in supported chipsets.
-
-KumeranLockLoss
----------------
-:Valid Range: 0,1
-:Default Value: 1 (enabled)
-
-This workaround skips resetting the PHY at shutdown for the initial silicon
-releases of ICH8 systems.
-
-IntMode
--------
-:Valid Range: 0-2
-:Default Value: 0
-
-   +-------+----------------+
-   | Value | Interrupt Mode |
-   +=======+================+
-   |   0   |     Legacy     |
-   +-------+----------------+
-   |   1   |       MSI      |
-   +-------+----------------+
-   |   2   |      MSI-X     |
-   +-------+----------------+
-
-IntMode allows load time control over the type of interrupt registered for by
-the driver. MSI-X is required for multiple queue support, and some kernels and
-combinations of kernel .config options will force a lower level of interrupt
-support.
-
-This command will show different values for each type of interrupt::
-
-  cat /proc/interrupts
-
-CrcStripping
-------------
-:Valid Range: 0,1
-:Default Value: 1 (enabled)
-
-Strip the CRC from received packets before sending up the network stack. If
-you have a machine with a BMC enabled but cannot receive IPMI traffic after
-loading or enabling the driver, try disabling this feature.
-
-WriteProtectNVM
----------------
-:Valid Range: 0,1
-:Default Value: 1 (enabled)
-
-If set to 1, configure the hardware to ignore all write/erase cycles to the
-GbE region in the ICHx NVM (in order to prevent accidental corruption of the
-NVM). This feature can be disabled by setting the parameter to 0 during initial
-driver load.
-
-NOTE: The machine must be power cycled (full off/on) when enabling NVM writes
-via setting the parameter to zero. Once the NVM has been locked (via the
-parameter at 1 when the driver loads) it cannot be unlocked except via power
-cycle.
-
-Debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-This parameter adjusts the level of debug messages displayed in the system logs.
-
-
-Additional Features and Configurations
-======================================
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-    ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-    ip link set mtu 9000 dev eth<x>
-    ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file:
-
-- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
-- For SLES: /etc/sysconfig/network/<config_file>
-
-NOTE: The maximum MTU setting for Jumbo Frames is 8996. This value coincides
-with the maximum Jumbo Frames size of 9018 bytes.
-
-NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
-poor performance or loss of link.
-
-NOTE: The following adapters limit Jumbo Frames sized packets to a maximum of
-4088 bytes:
-
-  - Intel(R) 82578DM Gigabit Network Connection
-  - Intel(R) 82577LM Gigabit Network Connection
-
-The following adapters do not support Jumbo Frames:
-
-  - Intel(R) PRO/1000 Gigabit Server Adapter
-  - Intel(R) PRO/1000 PM Network Connection
-  - Intel(R) 82562G 10/100 Network Connection
-  - Intel(R) 82562G-2 10/100 Network Connection
-  - Intel(R) 82562GT 10/100 Network Connection
-  - Intel(R) 82562GT-2 10/100 Network Connection
-  - Intel(R) 82562V 10/100 Network Connection
-  - Intel(R) 82562V-2 10/100 Network Connection
-  - Intel(R) 82566DC Gigabit Network Connection
-  - Intel(R) 82566DC-2 Gigabit Network Connection
-  - Intel(R) 82566DM Gigabit Network Connection
-  - Intel(R) 82566MC Gigabit Network Connection
-  - Intel(R) 82566MM Gigabit Network Connection
-  - Intel(R) 82567V-3 Gigabit Network Connection
-  - Intel(R) 82577LC Gigabit Network Connection
-  - Intel(R) 82578DC Gigabit Network Connection
-
-NOTE: Jumbo Frames cannot be configured on an 82579-based Network device if
-MACSec is enabled on the system.
-
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-
-https://www.kernel.org/pub/software/network/ethtool/
-
-NOTE: When validating enable/disable tests on some parts (for example, 82578),
-it is necessary to add a few seconds between tests when working with ethtool.
-
-
-Speed and Duplex Configuration
-------------------------------
-In addressing speed and duplex configuration issues, you need to distinguish
-between copper-based adapters and fiber-based adapters.
-
-In the default mode, an Intel(R) Ethernet Network Adapter using copper
-connections will attempt to auto-negotiate with its link partner to determine
-the best setting. If the adapter cannot establish link with the link partner
-using auto-negotiation, you may need to manually configure the adapter and link
-partner to identical settings to establish link and pass packets. This should
-only be needed when attempting to link with an older switch that does not
-support auto-negotiation or one that has been forced to a specific speed or
-duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
-and higher cannot be forced. Use the autonegotiation advertising setting to
-manually set devices for 1 Gbps and higher.
-
-Speed, duplex, and autonegotiation advertising are configured through the
-ethtool* utility.
-
-Caution: Only experienced network administrators should force speed and duplex
-or change autonegotiation advertising manually. The settings at the switch must
-always match the adapter settings. Adapter performance may suffer or your
-adapter may not operate if you configure the adapter differently from your
-switch.
-
-An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
-will not attempt to auto-negotiate with its link partner since those adapters
-operate only in full duplex and only at their native speed.
-
-
-Enabling Wake on LAN* (WoL)
----------------------------
-WoL is configured through the ethtool* utility.
-
-WoL will be enabled on the system during the next shut down or reboot. For
-this driver version, in order to enable WoL, the e1000e driver must be loaded
-prior to shutting down or suspending the system.
-
-NOTE: Wake on LAN is only supported on port A for the following devices:
-- Intel(R) PRO/1000 PT Dual Port Network Connection
-- Intel(R) PRO/1000 PT Dual Port Server Connection
-- Intel(R) PRO/1000 PT Dual Port Server Adapter
-- Intel(R) PRO/1000 PF Dual Port Server Adapter
-- Intel(R) PRO/1000 PT Quad Port Server Adapter
-- Intel(R) Gigabit PT Quad Port Server ExpressModule

+
+Identifying Your Adapter
+========================
+The driver is compatible with devices based on the following:
+
+ * Intel(R) Ethernet Controller X710
+ * Intel(R) Ethernet Controller XL710
+ * Intel(R) Ethernet Network Connection X722
+ * Intel(R) Ethernet Controller XXV710
+
+For the best performance, make sure the latest NVM/FW is installed on your
+device.
+
+For information on how to identify your adapter, and for the latest NVM/FW
+images and Intel network drivers, refer to the Intel Support website:
+https://www.intel.com/support
+
+SFP+ and QSFP+ Devices
+----------------------
+For information about supported media, refer to this document:
+https://www.intel.com/content/dam/www/public/us/en/documents/release-notes/xl710-ethernet-controller-feature-matrix.pdf
+
+NOTE: Some adapters based on the Intel(R) Ethernet Controller 700 Series only
+support Intel Ethernet Optics modules. On these adapters, other modules are not
+supported and will not function.  In all cases Intel recommends using Intel
+Ethernet Optics; other modules may function but are not validated by Intel.
+Contact Intel for supported media types.
+
+NOTE: For connections based on Intel(R) Ethernet Controller 700 Series, support
+is dependent on your system board. Please see your vendor for details.
+
+NOTE: In systems that do not have adequate airflow to cool the adapter and
+optical modules, you must use high temperature optical modules.
+
+Virtual Functions (VFs)
+-----------------------
+Use sysfs to enable VFs. For example::
+
+  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs #enable VFs
+  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs #disable VFs
+
+For example, the following instructions will configure PF eth0 and the first VF
+on VLAN 10::
+
+  $ ip link set dev eth0 vf 0 vlan 10
+
+VLAN Tag Packet Steering
+------------------------
+Allows you to send all packets with a specific VLAN tag to a particular SR-IOV
+virtual function (VF). Further, this feature allows you to designate a
+particular VF as trusted, and allows that trusted VF to request selective
+promiscuous mode on the Physical Function (PF).
+
+To set a VF as trusted or untrusted, enter the following command in the
+Hypervisor::
+
+  # ip link set dev eth0 vf 1 trust [on|off]
+
+Once the VF is designated as trusted, use the following commands in the VM to
+set the VF to promiscuous mode.
+
+::
+
+  For promiscuous all:
+  #ip link set eth2 promisc on
+  Where eth2 is a VF interface in the VM
+
+  For promiscuous Multicast:
+  #ip link set eth2 allmulticast on
+  Where eth2 is a VF interface in the VM
+
+NOTE: By default, the ethtool priv-flag vf-true-promisc-support is set to
+"off",meaning that promiscuous mode for the VF will be limited. To set the
+promiscuous mode for the VF to true promiscuous and allow the VF to see all
+ingress traffic, use the following command::
+
+  #ethtool -set-priv-flags p261p1 vf-true-promisc-support on
+
+The vf-true-promisc-support priv-flag does not enable promiscuous mode; rather,
+it designates which type of promiscuous mode (limited or true) you will get
+when you enable promiscuous mode using the ip link commands above. Note that
+this is a global setting that affects the entire device. However,the
+vf-true-promisc-support priv-flag is only exposed to the first PF of the
+device. The PF remains in limited promiscuous mode (unless it is in MFP mode)
+regardless of the vf-true-promisc-support setting.
+
+Now add a VLAN interface on the VF interface::
+
+  #ip link add link eth2 name eth2.100 type vlan id 100
+
+Note that the order in which you set the VF to promiscuous mode and add the
+VLAN interface does not matter (you can do either first). The end result in
+this example is that the VF will get all traffic that is tagged with VLAN 100.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+  balancing (in SFP mode only).
+
+NOTE: The Linux i40e driver supports the following flow types: IPv4, TCPv4, and
+UDPv4. For a given flow type, it supports valid combinations of IP addresses
+(source or destination) and UDP/TCP ports (source and destination). For
+example, you can supply only a source IP address, a source IP address and a
+destination port, or any combination of one or more of these four parameters.
+
+NOTE: The Linux i40e driver allows you to filter traffic based on a
+user-defined flexible two-byte pattern and offset by using the ethtool user-def
+and mask fields. Only L3 and L4 flow types are supported for user-defined
+flexible filters. For a given flow type, you must clear all Intel Ethernet Flow
+Director filters before changing the input set (for that flow type).
+
+To enable or disable the Intel Ethernet Flow Director::
+
+  # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To set a filter using only the source and destination IP address::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+  # ethtool <-u|-n> ethX
+
+Application Targeted Routing (ATR) Perfect Filters
+--------------------------------------------------
+ATR is enabled by default when the kernel is in multiple transmit queue mode.
+An ATR Intel Ethernet Flow Director filter rule is added when a TCP-IP flow
+starts and is deleted when the flow ends. When a TCP-IP Intel Ethernet Flow
+Director rule is added from ethtool (Sideband filter), ATR is turned off by the
+driver. To re-enable ATR, the sideband can be disabled with the ethtool -K
+option. For example::
+
+  ethtool –K [adapter] ntuple [off|on]
+
+If sideband is re-enabled after ATR is re-enabled, ATR remains enabled until a
+TCP-IP flow is added. When all TCP-IP sideband rules are deleted, ATR is
+automatically re-enabled.
+
+Packets that match the ATR rules are counted in fdir_atr_match stats in
+ethtool, which also can be used to verify whether ATR rules still exist.
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+  dst-port <port> action <queue>
+
+Where:
+  <device> - the ethernet device to program
+  <type> - can be ip4, tcp4, udp4, or sctp4
+  <ip> - the ip address to match on
+  <port> - the port number to match on
+  <queue> - the queue to direct traffic towards (-1 discards matching traffic)
+
+Use the following command to display all of the active filters::
+
+  ethtool -u <device>
+
+Use the following command to delete a filter::
+
+  ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+  src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two tcp4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the i40e driver, thus
+partial mask fields are not supported.
+
+The driver also supports matching user-defined data within the packet payload.
+This flexible data is specified using the "user-def" field of the ethtool
+command in the following way:
+
++----------------------------+--------------------------+
+| 31    28    24    20    16 | 15    12    8    4    0  |
++----------------------------+--------------------------+
+| offset into packet payload | 2 bytes of flexible data |
++----------------------------+--------------------------+
+
+For example,
+
+::
+
+  ... user-def 0x4FFFF ...
+
+tells the filter to look 4 bytes into the payload and match that value against
+0xFFFF. The offset is based on the beginning of the payload, and not the
+beginning of the packet. Thus
+
+::
+
+  flow-type tcp4 ... user-def 0x8BEAF ...
+
+would match TCP/IPv4 packets which have the value 0xBEAF 8 bytes into the
+TCP/IPv4 payload.
+
+Note that ICMP headers are parsed as 4 bytes of header and 4 bytes of payload.
+Thus to match the first byte of the payload, you must actually add 4 bytes to
+the offset. Also note that ip4 filters match both ICMP frames as well as raw
+(unknown) ip4 frames, where the payload will be the L3 payload of the IP4 frame.
+
+The maximum offset is 64. The hardware will only read up to 64 bytes of data
+from the payload. The offset must be even because the flexible data is 2 bytes
+long and must be aligned to byte 0 of the packet payload.
+
+The user-defined flexible offset is also considered part of the input set and
+cannot be programmed separately for multiple filters of the same type. However,
+the flexible data is not part of the input set and multiple filters may use the
+same offset but match against different data.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"action" parameter. Specify the action as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+  ... action 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Setting the link-down-on-close Private Flag
+-------------------------------------------
+When the link-down-on-close private flag is set to "on", the port's link will
+go down when the interface is brought down using the ifconfig ethX down command.
+
+Use ethtool to view and set link-down-on-close, as follows::
+
+  ethtool --show-priv-flags ethX
+  ethtool --set-priv-flags ethX link-down-on-close [on|off]
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+  dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+  ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+  ip link set mtu 9000 dev eth<x>
+  ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+  /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9702. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+Supported ethtool Commands and Options for Filtering

+udp6 UDP over IPv6
+
+f Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+n Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+Speed and Duplex Configuration
+------------------------------
+In addressing speed and duplex configuration issues, you need to distinguish
+between copper-based adapters and fiber-based adapters.
+
+In the default mode, an Intel(R) Ethernet Network Adapter using copper
+connections will attempt to auto-negotiate with its link partner to determine
+the best setting. If the adapter cannot establish link with the link partner
+using auto-negotiation, you may need to manually configure the adapter and link
+partner to identical settings to establish link and pass packets. This should
+only be needed when attempting to link with an older switch that does not
+support auto-negotiation or one that has been forced to a specific speed or
+duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
+and higher cannot be forced. Use the autonegotiation advertising setting to
+manually set devices for 1 Gbps and higher.
+
+NOTE: You cannot set the speed for devices based on the Intel(R) Ethernet
+Network Adapter XXV710 based devices.
+
+Speed, duplex, and autonegotiation advertising are configured through the
+ethtool* utility.
+
+Caution: Only experienced network administrators should force speed and duplex
+or change autonegotiation advertising manually. The settings at the switch must
+always match the adapter settings. Adapter performance may suffer or your
+adapter may not operate if you configure the adapter differently from your
+switch.
+
+An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
+will not attempt to auto-negotiate with its link partner since those adapters
+operate only in full duplex and only at their native speed.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the i40e driver.
+For more information on NAPI, see
+https://wiki.linuxfoundation.org/networking/napi
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for i40e. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is on by default.
+
+Use ethtool to change the flow control settings.
+
+To enable or disable Rx or Tx Flow Control::
+
+  ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+  ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+RSS Hash Flow
+-------------
+Allows you to set the hash bytes per flow type and any combination of one or
+more options for Receive Side Scaling (RSS) hash byte configuration.
+
+::
+
+  # ethtool -N <dev> rx-flow-hash <type> <option>
+
+Where <type> is:
+  tcp4	signifying TCP over IPv4
+  udp4	signifying UDP over IPv4
+  tcp6	signifying TCP over IPv6
+  udp6	signifying UDP over IPv6
+And <option> is one or more of:
+  s	Hash on the IP source address of the Rx packet.
+  d	Hash on the IP destination address of the Rx packet.
+  f	Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
+  n	Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+  ip link set <pf dev> vf <vf id> spoofchk {off|on}
+
+IEEE 1588 Precision Time Protocol (PTP) Hardware Clock (PHC)
+------------------------------------------------------------
+Precision Time Protocol (PTP) is used to synchronize clocks in a computer
+network. PTP support varies among Intel devices that support this driver. Use
+"ethtool -T <netdev name>" to get a definitive list of PTP capabilities
+supported by the device.
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+  Receive checksum offloads, cloud filters, and VLAN acceleration are not
+  supported for 802.1ad (QinQ) packets.
+
+VXLAN and GENEVE Overlay HW Offloading
+--------------------------------------
+Virtual Extensible LAN (VXLAN) allows you to extend an L2 network over an L3
+network, which may be useful in a virtualized or cloud environment. Some
+Intel(R) Ethernet Network devices perform VXLAN processing, offloading it from
+the operating system. This reduces CPU utilization.
+
+VXLAN offloading is controlled by the Tx and Rx checksum offload options
+provided by ethtool. That is, if Tx checksum offload is enabled, and the
+adapter has the capability, VXLAN offloading is also enabled.
+
+Support for VXLAN and GENEVE HW offloading is dependent on kernel support of
+the HW offloading features.
+
+Multiple Functions per Port
+---------------------------
+Some adapters based on the Intel Ethernet Controller X710/XL710 support
+multiple functions on a single physical port. Configure these functions through
+the System Setup/BIOS.
+
+Minimum TX Bandwidth is the guaranteed minimum data transmission bandwidth, as
+a percentage of the full physical port link speed, that the partition will
+receive. The bandwidth the partition is awarded will never fall below the level
+you specify.
+
+The range for the minimum bandwidth values is:
+1 to ((100 minus # of partitions on the physical port) plus 1)
+For example, if a physical port has 4 partitions, the range would be:
+1 to ((100 - 4) + 1 = 97)
+
+The Maximum Bandwidth percentage represents the maximum transmit bandwidth
+allocated to the partition as a percentage of the full physical port link
+speed. The accepted range of values is 1-100. The value is used as a limiter,
+should you chose that any one particular function not be able to consume 100%
+of a port's bandwidth (should it be available). The sum of all the values for
+Maximum Bandwidth is not restricted, because no more than 100% of a port's
+bandwidth can ever be used.
+
+NOTE: X710/XXV710 devices fail to enable Max VFs (64) when Multiple Functions
+per Port (MFP) and SR-IOV are enabled. An error from i40e is logged that says
+"add vsi failed for VF N, aq_err 16". To workaround the issue, enable less than
+64 virtual functions (VFs).
+
+Data Center Bridging (DCB)
+--------------------------
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+NOTE: Firmware LLDP can be disabled by setting the private flag disable-fw-lldp.
+
+The i40e driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+Interrupt Rate Limiting
+-----------------------
+:Valid Range: 0-235 (0=no limit)
+
+The Intel(R) Ethernet Controller XL710 family supports an interrupt rate
+limiting mechanism. The user can control, via ethtool, the number of
+microseconds between interrupts.
+
+Syntax::
+
+  # ethtool -C ethX rx-usecs-high N
+
+The range of 0-235 microseconds provides an effective range of 4,310 to 250,000
+interrupts per second. The value of rx-usecs-high can be set independently of
+rx-usecs and tx-usecs in the same ethtool command, and is also independent of
+the adaptive interrupt moderation algorithm. The underlying hardware supports
+granularity in 4-microsecond intervals, so adjacent values may result in the
+same interrupt rate.
+
+One possible use case is the following::
+
+  # ethtool -C ethX adaptive-rx off adaptive-tx off rx-usecs-high 20 rx-usecs \
+    5 tx-usecs 5
+
+The above command would disable adaptive interrupt moderation, and allow a
+maximum of 5 microseconds before indicating a receive or transmit was complete.
+However, instead of resulting in as many as 200,000 interrupts per second, it
+limits total interrupts per second to 50,000 via the rx-usecs-high parameter.
+
+Performance Optimization
+========================
+Driver defaults are meant to fit a wide variety of workloads, but if further
+optimization is required we recommend experimenting with the following settings.
+
+NOTE: For better performance when processing small (64B) frame sizes, try
+enabling Hyper threading in the BIOS in order to increase the number of logical
+cores in the system and subsequently increase the number of queues available to
+the adapter.
+
+Virtualized Environments
+------------------------
+1. Disable XPS on both ends by using the included virt_perf_default script
+or by running the following command as root::
+
+  for file in `ls /sys/class/net/<ethX>/queues/tx-*/xps_cpus`;
+  do echo 0 > $file; done
+
+2. Using the appropriate mechanism (vcpupin) in the vm, pin the cpu's to
+individual lcpu's, making sure to use a set of cpu's included in the
+device's local_cpulist: /sys/class/net/<ethX>/device/local_cpulist.
+
+3. Configure as many Rx/Tx queues in the VM as available. Do not rely on
+the default setting of 1.
+
+
+Non-virtualized Environments
+----------------------------
+Pin the adapter's IRQs to specific cores by disabling the irqbalance service
+and using the included set_irq_affinity script. Please see the script's help
+text for further options.
+
+- The following settings will distribute the IRQs across all the cores evenly::
+
+  # scripts/set_irq_affinity -x all <interface1> , [ <interface2>, ... ]
+
+- The following settings will distribute the IRQs across all the cores that are
+  local to the adapter (same NUMA node)::
+
+  # scripts/set_irq_affinity -x local <interface1> ,[ <interface2>, ... ]
+
+For very CPU intensive workloads, we recommend pinning the IRQs to all cores.
+
+For IP Forwarding: Disable Adaptive ITR and lower Rx and Tx interrupts per
+queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 125 will limit interrupts to about 8000
+  interrupts per second per queue.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 125 \
+    tx-usecs 125
+
+For lower CPU utilization: Disable Adaptive ITR and lower Rx and Tx interrupts
+per queue using ethtool.
+
+- Setting rx-usecs and tx-usecs to 250 will limit interrupts to about 4000
+  interrupts per second per queue.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 250 \
+    tx-usecs 250
+
+For lower latency: Disable Adaptive ITR and ITR by setting Rx and Tx to 0 using
+ethtool.
+
+::
+
+  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 0 \
+    tx-usecs 0
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+  # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+  max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+2. Enable HW TC offload on interface::
+
+    # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+    # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
+ - ADq is not compatible with cloud filters.
+ - Setting up channels via ethtool (ethtool -L) is not supported when the
+   TCs are configured using mqprio.
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required.
+ - ADq cannot be enabled when any the following features are enabled: Data
+   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband
+   Filters.
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+   enable ADq.
+ - Tunnel filters are not supported in ADq. If encapsulated packets do
+   arrive in non-tunnel mode, filtering will be done on the inner headers.
+   For example, for VXLAN traffic in non-tunnel mode, PCTYPE is identified
+   as a VXLAN encapsulated packet, outer headers are ignored. Therefore,
+   inner headers are matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that
+   traffic will be routed to the appropriate queue of the PF, and will
+   not be passed on the VF. Such traffic will end up getting dropped higher
+   up in the TCP/IP stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs,
+   that traffic will be duplicated and sent to all matching TC queues.
+   The hardware switch mirrors the packet to a VSI list when multiple
+   filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE: 1 Gb devices based on the Intel(R) Ethernet Network Connection X722 do
+not support the following features:
+
+  * Data Center Bridging (DCB)
+  * QOS
+  * VMQ
+  * SR-IOV
+  * Task Encapsulation offload (VXLAN, NVGRE)
+  * Energy Efficient Ethernet (EEE)
+  * Auto-media detect
+
+Unexpected Issues when the device driver and DPDK share a device
+----------------------------------------------------------------
+Unexpected issues may result when an i40e device is in multi driver mode and
+the kernel driver and DPDK driver are sharing the device. This is because
+access to the global NIC resources is not synchronized between multiple
+drivers. Any change to the global NIC configuration (writing to a global
+register, setting global configuration by AQ, or changing switch modes) will
+affect all ports and drivers on the device. Loading DPDK with the
+"multi-driver" module parameter may mitigate some of the issues.
+
+TC0 must be enabled when setting up DCB on a switch
+---------------------------------------------------
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.

-Identifying Your Adapter
-========================
-The driver is compatible with devices based on the following:
-
- * Intel(R) Ethernet Controller X710
- * Intel(R) Ethernet Controller XL710
- * Intel(R) Ethernet Network Connection X722
- * Intel(R) Ethernet Controller XXV710
-
-For the best performance, make sure the latest NVM/FW is installed on your
-device.

-SFP+ and QSFP+ Devices
-----------------------
-For information about supported media, refer to this document:
-https://www.intel.com/content/dam/www/public/us/en/documents/release-notes/xl710-ethernet-controller-feature-matrix.pdf
-
-NOTE: Some adapters based on the Intel(R) Ethernet Controller 700 Series only
-support Intel Ethernet Optics modules. On these adapters, other modules are not
-supported and will not function.  In all cases Intel recommends using Intel
-Ethernet Optics; other modules may function but are not validated by Intel.
-Contact Intel for supported media types.
-
-NOTE: For connections based on Intel(R) Ethernet Controller 700 Series, support
-is dependent on your system board. Please see your vendor for details.
-
-NOTE: In systems that do not have adequate airflow to cool the adapter and
-optical modules, you must use high temperature optical modules.
-
-Virtual Functions (VFs)
------------------------
-Use sysfs to enable VFs. For example::
-
-  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs #enable VFs
-  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs #disable VFs
-
-For example, the following instructions will configure PF eth0 and the first VF
-on VLAN 10::
-
-  $ ip link set dev eth0 vf 0 vlan 10
-
-VLAN Tag Packet Steering
-------------------------
-Allows you to send all packets with a specific VLAN tag to a particular SR-IOV
-virtual function (VF). Further, this feature allows you to designate a
-particular VF as trusted, and allows that trusted VF to request selective
-promiscuous mode on the Physical Function (PF).
-
-To set a VF as trusted or untrusted, enter the following command in the
-Hypervisor::
-
-  # ip link set dev eth0 vf 1 trust [on|off]
-
-Once the VF is designated as trusted, use the following commands in the VM to
-set the VF to promiscuous mode.
-
-::
-
-  For promiscuous all:
-  #ip link set eth2 promisc on
-  Where eth2 is a VF interface in the VM
-
-  For promiscuous Multicast:
-  #ip link set eth2 allmulticast on
-  Where eth2 is a VF interface in the VM
-
-NOTE: By default, the ethtool priv-flag vf-true-promisc-support is set to
-"off",meaning that promiscuous mode for the VF will be limited. To set the
-promiscuous mode for the VF to true promiscuous and allow the VF to see all
-ingress traffic, use the following command::
-
-  #ethtool -set-priv-flags p261p1 vf-true-promisc-support on
-
-The vf-true-promisc-support priv-flag does not enable promiscuous mode; rather,
-it designates which type of promiscuous mode (limited or true) you will get
-when you enable promiscuous mode using the ip link commands above. Note that
-this is a global setting that affects the entire device. However,the
-vf-true-promisc-support priv-flag is only exposed to the first PF of the
-device. The PF remains in limited promiscuous mode (unless it is in MFP mode)
-regardless of the vf-true-promisc-support setting.
-
-Now add a VLAN interface on the VF interface::
-
-  #ip link add link eth2 name eth2.100 type vlan id 100
-
-Note that the order in which you set the VF to promiscuous mode and add the
-VLAN interface does not matter (you can do either first). The end result in
-this example is that the VF will get all traffic that is tagged with VLAN 100.
-
-Intel(R) Ethernet Flow Director
--------------------------------
-The Intel Ethernet Flow Director performs the following tasks:
-
-- Directs receive packets according to their flows to different queues.
-- Enables tight control on routing a flow in the platform.
-- Matches flows and CPU cores for flow affinity.
-- Supports multiple parameters for flexible flow classification and load
-  balancing (in SFP mode only).
-
-NOTE: The Linux i40e driver supports the following flow types: IPv4, TCPv4, and
-UDPv4. For a given flow type, it supports valid combinations of IP addresses
-(source or destination) and UDP/TCP ports (source and destination). For
-example, you can supply only a source IP address, a source IP address and a
-destination port, or any combination of one or more of these four parameters.
-
-NOTE: The Linux i40e driver allows you to filter traffic based on a
-user-defined flexible two-byte pattern and offset by using the ethtool user-def
-and mask fields. Only L3 and L4 flow types are supported for user-defined
-flexible filters. For a given flow type, you must clear all Intel Ethernet Flow
-Director filters before changing the input set (for that flow type).
-
-To enable or disable the Intel Ethernet Flow Director::
-
-  # ethtool -K ethX ntuple <on|off>
-
-When disabling ntuple filters, all the user programmed filters are flushed from
-the driver cache and hardware. All needed filters must be re-added when ntuple
-is re-enabled.
-
-To add a filter that directs packet to queue 2, use -U or -N switch::
-
-  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
-  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
-
-To set a filter using only the source and destination IP address::
-
-  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
-  192.168.10.2 action 2 [loc 1]
-
-To see the list of filters currently present::
-
-  # ethtool <-u|-n> ethX
-
-Application Targeted Routing (ATR) Perfect Filters
---------------------------------------------------
-ATR is enabled by default when the kernel is in multiple transmit queue mode.
-An ATR Intel Ethernet Flow Director filter rule is added when a TCP-IP flow
-starts and is deleted when the flow ends. When a TCP-IP Intel Ethernet Flow
-Director rule is added from ethtool (Sideband filter), ATR is turned off by the
-driver. To re-enable ATR, the sideband can be disabled with the ethtool -K
-option. For example::
-
-  ethtool –K [adapter] ntuple [off|on]
-
-If sideband is re-enabled after ATR is re-enabled, ATR remains enabled until a
-TCP-IP flow is added. When all TCP-IP sideband rules are deleted, ATR is
-automatically re-enabled.
-
-Packets that match the ATR rules are counted in fdir_atr_match stats in
-ethtool, which also can be used to verify whether ATR rules still exist.
-
-Sideband Perfect Filters
-------------------------
-Sideband Perfect Filters are used to direct traffic that matches specified
-characteristics. They are enabled through ethtool's ntuple interface. To add a
-new filter use the following command::
-
-  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
-  dst-port <port> action <queue>
-
-Where:
-  <device> - the ethernet device to program
-  <type> - can be ip4, tcp4, udp4, or sctp4
-  <ip> - the ip address to match on
-  <port> - the port number to match on
-  <queue> - the queue to direct traffic towards (-1 discards matching traffic)
-
-Use the following command to display all of the active filters::
-
-  ethtool -u <device>
-
-Use the following command to delete a filter::
-
-  ethtool -U <device> delete <N>
-
-Where <N> is the filter id displayed when printing all the active filters, and
-may also have been specified using "loc <N>" when adding the filter.
-
-The following example matches TCP traffic sent from 192.168.0.1, port 5300,
-directed to 192.168.0.5, port 80, and sends it to queue 7::
-
-  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
-  src-port 5300 dst-port 80 action 7
-
-For each flow-type, the programmed filters must all have the same matching
-input set. For example, issuing the following two commands is acceptable::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
-
-Issuing the next two commands, however, is not acceptable, since the first
-specifies src-ip and the second specifies dst-ip::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
-
-The second command will fail with an error. You may program multiple filters
-with the same fields, using different values, but, on one device, you may not
-program two tcp4 filters with different matching fields.
-
-Matching on a sub-portion of a field is not supported by the i40e driver, thus
-partial mask fields are not supported.
-
-The driver also supports matching user-defined data within the packet payload.
-This flexible data is specified using the "user-def" field of the ethtool
-command in the following way:

-+----------------------------+--------------------------+
-| offset into packet payload | 2 bytes of flexible data |
-+----------------------------+--------------------------+
-
-For example,
-
-::
-
-  ... user-def 0x4FFFF ...
-
-tells the filter to look 4 bytes into the payload and match that value against
-0xFFFF. The offset is based on the beginning of the payload, and not the
-beginning of the packet. Thus
-
-::
-
-  flow-type tcp4 ... user-def 0x8BEAF ...
-
-would match TCP/IPv4 packets which have the value 0xBEAF 8 bytes into the
-TCP/IPv4 payload.
-
-Note that ICMP headers are parsed as 4 bytes of header and 4 bytes of payload.
-Thus to match the first byte of the payload, you must actually add 4 bytes to
-the offset. Also note that ip4 filters match both ICMP frames as well as raw
-(unknown) ip4 frames, where the payload will be the L3 payload of the IP4 frame.
-
-The maximum offset is 64. The hardware will only read up to 64 bytes of data
-from the payload. The offset must be even because the flexible data is 2 bytes
-long and must be aligned to byte 0 of the packet payload.
-
-The user-defined flexible offset is also considered part of the input set and
-cannot be programmed separately for multiple filters of the same type. However,
-the flexible data is not part of the input set and multiple filters may use the
-same offset but match against different data.
-
-To create filters that direct traffic to a specific Virtual Function, use the
-"action" parameter. Specify the action as a 64 bit value, where the lower 32
-bits represents the queue number, while the next 8 bits represent which VF.
-Note that 0 is the PF, so the VF identifier is offset by 1. For example::
-
-  ... action 0x800000002 ...
-
-specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
-that VF.
-
-Note that these filters will not break internal routing rules, and will not
-route traffic that otherwise would not have been sent to the specified Virtual
-Function.
-
-Setting the link-down-on-close Private Flag
--------------------------------------------
-When the link-down-on-close private flag is set to "on", the port's link will
-go down when the interface is brought down using the ifconfig ethX down command.
-
-Use ethtool to view and set link-down-on-close, as follows::
-
-  ethtool --show-priv-flags ethX
-  ethtool --set-priv-flags ethX link-down-on-close [on|off]
-
-Viewing Link Messages
----------------------
-Link messages will not be displayed to the console if the distribution is
-restricting system messages. In order to see network driver link messages on
-your console, set dmesg to eight by entering the following::
-
-  dmesg -n 8
-
-NOTE: This setting is not saved across reboots.
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-  ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-  ip link set mtu 9000 dev eth<x>
-  ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file::
-
-  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
-  /etc/sysconfig/network/<config_file> // for SLES
-
-NOTE: The maximum MTU setting for Jumbo Frames is 9702. This value coincides
-with the maximum Jumbo Frames size of 9728 bytes.
-
-NOTE: This driver will attempt to use multiple page sized buffers to receive
-each jumbo packet. This should help to avoid buffer starvation issues when
-allocating receive packets.
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-https://www.kernel.org/pub/software/network/ethtool/
-
-Supported ethtool Commands and Options for Filtering
-----------------------------------------------------
--n --show-nfc
-  Retrieves the receive network flow classification configurations.
-
-rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6
-  Retrieves the hash options for the specified network traffic type.
-
--N --config-nfc
-  Configures the receive network flow classification.
-
-rx-flow-hash tcp4|udp4|ah4|esp4|sctp4|tcp6|udp6|ah6|esp6|sctp6 m|v|t|s|d|f|n|r...
-  Configures the hash options for the specified network traffic type.
-
-udp4 UDP over IPv4
-udp6 UDP over IPv6
-
-f Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
-n Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
-
-Speed and Duplex Configuration
-------------------------------
-In addressing speed and duplex configuration issues, you need to distinguish
-between copper-based adapters and fiber-based adapters.
-
-In the default mode, an Intel(R) Ethernet Network Adapter using copper
-connections will attempt to auto-negotiate with its link partner to determine
-the best setting. If the adapter cannot establish link with the link partner
-using auto-negotiation, you may need to manually configure the adapter and link
-partner to identical settings to establish link and pass packets. This should
-only be needed when attempting to link with an older switch that does not
-support auto-negotiation or one that has been forced to a specific speed or
-duplex mode. Your link partner must match the setting you choose. 1 Gbps speeds
-and higher cannot be forced. Use the autonegotiation advertising setting to
-manually set devices for 1 Gbps and higher.
-
-NOTE: You cannot set the speed for devices based on the Intel(R) Ethernet
-Network Adapter XXV710 based devices.
-
-Speed, duplex, and autonegotiation advertising are configured through the
-ethtool* utility.
-
-Caution: Only experienced network administrators should force speed and duplex
-or change autonegotiation advertising manually. The settings at the switch must
-always match the adapter settings. Adapter performance may suffer or your
-adapter may not operate if you configure the adapter differently from your
-switch.
-
-An Intel(R) Ethernet Network Adapter using fiber-based connections, however,
-will not attempt to auto-negotiate with its link partner since those adapters
-operate only in full duplex and only at their native speed.
-
-NAPI
-----
-NAPI (Rx polling mode) is supported in the i40e driver.
-For more information on NAPI, see
-https://wiki.linuxfoundation.org/networking/napi
-
-Flow Control
-------------
-Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
-receiving and transmitting pause frames for i40e. When transmit is enabled,
-pause frames are generated when the receive packet buffer crosses a predefined
-threshold. When receive is enabled, the transmit unit will halt for the time
-delay specified when a pause frame is received.
-
-NOTE: You must have a flow control capable link partner.
-
-Flow Control is on by default.
-
-Use ethtool to change the flow control settings.
-
-To enable or disable Rx or Tx Flow Control::
-
-  ethtool -A eth? rx <on|off> tx <on|off>
-
-Note: This command only enables or disables Flow Control if auto-negotiation is
-disabled. If auto-negotiation is enabled, this command changes the parameters
-used for auto-negotiation with the link partner.
-
-To enable or disable auto-negotiation::
-
-  ethtool -s eth? autoneg <on|off>
-
-Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
-on your device, you may not be able to change the auto-negotiation setting.
-
-RSS Hash Flow
--------------
-Allows you to set the hash bytes per flow type and any combination of one or
-more options for Receive Side Scaling (RSS) hash byte configuration.
-
-::
-
-  # ethtool -N <dev> rx-flow-hash <type> <option>
-
-Where <type> is:
-  tcp4	signifying TCP over IPv4
-  udp4	signifying UDP over IPv4
-  tcp6	signifying TCP over IPv6
-  udp6	signifying UDP over IPv6
-And <option> is one or more of:
-  s	Hash on the IP source address of the Rx packet.
-  d	Hash on the IP destination address of the Rx packet.
-  f	Hash on bytes 0 and 1 of the Layer 4 header of the Rx packet.
-  n	Hash on bytes 2 and 3 of the Layer 4 header of the Rx packet.
-
-MAC and VLAN anti-spoofing feature
-----------------------------------
-When a malicious driver attempts to send a spoofed packet, it is dropped by the
-hardware and not transmitted.
-NOTE: This feature can be disabled for a specific Virtual Function (VF)::
-
-  ip link set <pf dev> vf <vf id> spoofchk {off|on}
-
-IEEE 1588 Precision Time Protocol (PTP) Hardware Clock (PHC)
-------------------------------------------------------------
-Precision Time Protocol (PTP) is used to synchronize clocks in a computer
-network. PTP support varies among Intel devices that support this driver. Use
-"ethtool -T <netdev name>" to get a definitive list of PTP capabilities
-supported by the device.
-
-IEEE 802.1ad (QinQ) Support
----------------------------
-The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
-IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
-"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
-allow L2 tunneling and the ability to segregate traffic within a particular
-VLAN ID, among other uses.
-
-The following are examples of how to configure 802.1ad (QinQ)::
-
-  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
-  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
-
-Where "24" and "371" are example VLAN IDs.
-
-NOTES:
-  Receive checksum offloads, cloud filters, and VLAN acceleration are not
-  supported for 802.1ad (QinQ) packets.
-
-VXLAN and GENEVE Overlay HW Offloading
---------------------------------------
-Virtual Extensible LAN (VXLAN) allows you to extend an L2 network over an L3
-network, which may be useful in a virtualized or cloud environment. Some
-Intel(R) Ethernet Network devices perform VXLAN processing, offloading it from
-the operating system. This reduces CPU utilization.
-
-VXLAN offloading is controlled by the Tx and Rx checksum offload options
-provided by ethtool. That is, if Tx checksum offload is enabled, and the
-adapter has the capability, VXLAN offloading is also enabled.
-
-Support for VXLAN and GENEVE HW offloading is dependent on kernel support of
-the HW offloading features.
-
-Multiple Functions per Port
----------------------------
-Some adapters based on the Intel Ethernet Controller X710/XL710 support
-multiple functions on a single physical port. Configure these functions through
-the System Setup/BIOS.
-
-Minimum TX Bandwidth is the guaranteed minimum data transmission bandwidth, as
-a percentage of the full physical port link speed, that the partition will
-receive. The bandwidth the partition is awarded will never fall below the level
-you specify.
-
-The range for the minimum bandwidth values is:
-1 to ((100 minus # of partitions on the physical port) plus 1)
-For example, if a physical port has 4 partitions, the range would be:
-1 to ((100 - 4) + 1 = 97)
-
-The Maximum Bandwidth percentage represents the maximum transmit bandwidth
-allocated to the partition as a percentage of the full physical port link
-speed. The accepted range of values is 1-100. The value is used as a limiter,
-should you chose that any one particular function not be able to consume 100%
-of a port's bandwidth (should it be available). The sum of all the values for
-Maximum Bandwidth is not restricted, because no more than 100% of a port's
-bandwidth can ever be used.
-
-NOTE: X710/XXV710 devices fail to enable Max VFs (64) when Multiple Functions
-per Port (MFP) and SR-IOV are enabled. An error from i40e is logged that says
-"add vsi failed for VF N, aq_err 16". To workaround the issue, enable less than
-64 virtual functions (VFs).
-
-Data Center Bridging (DCB)
---------------------------
-DCB is a configuration Quality of Service implementation in hardware. It uses
-the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
-different priorities that traffic can be filtered into. It also enables
-priority flow control (802.1Qbb) which can limit or eliminate the number of
-dropped packets during network stress. Bandwidth can be allocated to each of
-these priorities, which is enforced at the hardware level (802.1Qaz).
-
-Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
-802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
-and can accept settings from a DCBX capable peer. Software configuration of
-DCBX parameters via dcbtool/lldptool are not supported.
-
-NOTE: Firmware LLDP can be disabled by setting the private flag disable-fw-lldp.
-
-The i40e driver implements the DCB netlink interface layer to allow user-space
-to communicate with the driver and query DCB configuration for the port.
-
-NOTE:
-The kernel assumes that TC0 is available, and will disable Priority Flow
-Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
-enabled when setting up DCB on your switch.
-
-Interrupt Rate Limiting
------------------------
-:Valid Range: 0-235 (0=no limit)
-
-The Intel(R) Ethernet Controller XL710 family supports an interrupt rate
-limiting mechanism. The user can control, via ethtool, the number of
-microseconds between interrupts.
-
-Syntax::
-
-  # ethtool -C ethX rx-usecs-high N
-
-The range of 0-235 microseconds provides an effective range of 4,310 to 250,000
-interrupts per second. The value of rx-usecs-high can be set independently of
-rx-usecs and tx-usecs in the same ethtool command, and is also independent of
-the adaptive interrupt moderation algorithm. The underlying hardware supports
-granularity in 4-microsecond intervals, so adjacent values may result in the
-same interrupt rate.
-
-One possible use case is the following::
-
-  # ethtool -C ethX adaptive-rx off adaptive-tx off rx-usecs-high 20 rx-usecs \
-    5 tx-usecs 5
-
-The above command would disable adaptive interrupt moderation, and allow a
-maximum of 5 microseconds before indicating a receive or transmit was complete.
-However, instead of resulting in as many as 200,000 interrupts per second, it
-limits total interrupts per second to 50,000 via the rx-usecs-high parameter.
-
-Performance Optimization
-========================
-Driver defaults are meant to fit a wide variety of workloads, but if further
-optimization is required we recommend experimenting with the following settings.
-
-NOTE: For better performance when processing small (64B) frame sizes, try
-enabling Hyper threading in the BIOS in order to increase the number of logical
-cores in the system and subsequently increase the number of queues available to
-the adapter.
-
-Virtualized Environments
-------------------------
-1. Disable XPS on both ends by using the included virt_perf_default script
-or by running the following command as root::
-
-  for file in `ls /sys/class/net/<ethX>/queues/tx-*/xps_cpus`;
-  do echo 0 > $file; done
-
-2. Using the appropriate mechanism (vcpupin) in the vm, pin the cpu's to
-individual lcpu's, making sure to use a set of cpu's included in the
-device's local_cpulist: /sys/class/net/<ethX>/device/local_cpulist.
-
-3. Configure as many Rx/Tx queues in the VM as available. Do not rely on
-the default setting of 1.
-
-
-Non-virtualized Environments
-----------------------------
-Pin the adapter's IRQs to specific cores by disabling the irqbalance service
-and using the included set_irq_affinity script. Please see the script's help
-text for further options.
-
-- The following settings will distribute the IRQs across all the cores evenly::
-
-  # scripts/set_irq_affinity -x all <interface1> , [ <interface2>, ... ]
-
-- The following settings will distribute the IRQs across all the cores that are
-  local to the adapter (same NUMA node)::
-
-  # scripts/set_irq_affinity -x local <interface1> ,[ <interface2>, ... ]
-
-For very CPU intensive workloads, we recommend pinning the IRQs to all cores.
-
-For IP Forwarding: Disable Adaptive ITR and lower Rx and Tx interrupts per
-queue using ethtool.
-
-- Setting rx-usecs and tx-usecs to 125 will limit interrupts to about 8000
-  interrupts per second per queue.
-
-::
-
-  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 125 \
-    tx-usecs 125
-
-For lower CPU utilization: Disable Adaptive ITR and lower Rx and Tx interrupts
-per queue using ethtool.
-
-- Setting rx-usecs and tx-usecs to 250 will limit interrupts to about 4000
-  interrupts per second per queue.
-
-::
-
-  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 250 \
-    tx-usecs 250
-
-For lower latency: Disable Adaptive ITR and ITR by setting Rx and Tx to 0 using
-ethtool.
-
-::
-
-  # ethtool -C <interface> adaptive-rx off adaptive-tx off rx-usecs 0 \
-    tx-usecs 0
-
-Application Device Queues (ADq)
--------------------------------
-Application Device Queues (ADq) allows you to dedicate one or more queues to a
-specific application. This can reduce latency for the specified application,
-and allow Tx traffic to be rate limited per application. Follow the steps below
-to set ADq.
-
-1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
-The shaper bw_rlimit parameter is optional.
-
-Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
-to 1Gbit for tc0 and 3Gbit for tc1.
-
-::
-
-  # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
-  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
-  max_rate 1Gbit 3Gbit
-
-map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
-sets priorities 0-3 to use tc0 and 4-7 to use tc1)
-
-queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
-16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
-number of queues for all tcs is 64 or number of cores, whichever is lower.)
-
-hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
-offload mode in mqprio that makes full use of the mqprio options, the
-TCs, the queue configurations, and the QoS parameters.
-
-shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
-Totals must be equal or less than port speed.
-
-For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
-monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
-
-2. Enable HW TC offload on interface::
-
-    # ethtool -K <interface> hw-tc-offload on
-
-3. Apply TCs to ingress (RX) flow of interface::
-
-    # tc qdisc add dev <interface> ingress
-
-NOTES:
- - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
- - ADq is not compatible with cloud filters.
- - Setting up channels via ethtool (ethtool -L) is not supported when the
-   TCs are configured using mqprio.
- - You must have iproute2 latest version
- - NVM version 6.01 or later is required.
- - ADq cannot be enabled when any the following features are enabled: Data
-   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband
-   Filters.
- - If another driver (for example, DPDK) has set cloud filters, you cannot
-   enable ADq.
- - Tunnel filters are not supported in ADq. If encapsulated packets do
-   arrive in non-tunnel mode, filtering will be done on the inner headers.
-   For example, for VXLAN traffic in non-tunnel mode, PCTYPE is identified
-   as a VXLAN encapsulated packet, outer headers are ignored. Therefore,
-   inner headers are matched.
- - If a TC filter on a PF matches traffic over a VF (on the PF), that
-   traffic will be routed to the appropriate queue of the PF, and will
-   not be passed on the VF. Such traffic will end up getting dropped higher
-   up in the TCP/IP stack as it does not match PF address data.
- - If traffic matches multiple TC filters that point to different TCs,
-   that traffic will be duplicated and sent to all matching TC queues.
-   The hardware switch mirrors the packet to a VSI list when multiple
-   filters are matched.
-
-
-Known Issues/Troubleshooting
-============================
-
-NOTE: 1 Gb devices based on the Intel(R) Ethernet Network Connection X722 do
-not support the following features:
-
-  * Data Center Bridging (DCB)
-  * QOS
-  * VMQ
-  * SR-IOV
-  * Task Encapsulation offload (VXLAN, NVGRE)
-  * Energy Efficient Ethernet (EEE)
-  * Auto-media detect
-
-Unexpected Issues when the device driver and DPDK share a device
-----------------------------------------------------------------
-Unexpected issues may result when an i40e device is in multi driver mode and
-the kernel driver and DPDK driver are sharing the device. This is because
-access to the global NIC resources is not synchronized between multiple
-drivers. Any change to the global NIC configuration (writing to a global
-register, setting global configuration by AQ, or changing switch modes) will
-affect all ports and drivers on the device. Loading DPDK with the
-"multi-driver" module parameter may mitigate some of the issues.
-
-TC0 must be enabled when setting up DCB on a switch
----------------------------------------------------
-The kernel assumes that TC0 is available, and will disable Priority Flow
-Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
-enabled when setting up DCB on your switch.

+- Known Issues/Troubleshooting
+- Support
+
+This file describes the iavf Linux* Base Driver. This driver was formerly
+called i40evf.
+
+The iavf driver supports the below mentioned virtual function devices and
+can only be activated on kernels running the i40e or newer Physical Function
+(PF) driver compiled with CONFIG_PCI_IOV.  The iavf driver requires
+CONFIG_PCI_MSI to be enabled.
+
+The guest OS loading the iavf driver must support MSI-X interrupts.
+
+Identifying Your Adapter
+========================
+The driver in this kernel is compatible with devices based on the following:
+ * Intel(R) XL710 X710 Virtual Function
+ * Intel(R) X722 Virtual Function
+ * Intel(R) XXV710 Virtual Function
+ * Intel(R) Ethernet Adaptive Virtual Function
+
+For the best performance, make sure the latest NVM/FW is installed on your
+device.
+
+For information on how to identify your adapter, and for the latest NVM/FW
+images and Intel network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Additional Features and Configurations
+======================================
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+  dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+Setting VLAN Tag Stripping
+--------------------------
+If you have applications that require Virtual Functions (VFs) to receive
+packets with VLAN tags, you can disable VLAN tag stripping for the VF. The
+Physical Function (PF) processes requests issued from the VF to enable or
+disable VLAN tag stripping. Note that if the PF has assigned a VLAN to a VF,
+then requests from that VF to set VLAN tag stripping will be ignored.
+
+To enable/disable VLAN tag stripping for a VF, issue the following command
+from inside the VM in which you are running the VF::
+
+  ethtool -K <if_name> rxvlan on/off
+
+or alternatively::
+
+  ethtool --offload <if_name> rxvlan on/off
+
+Adaptive Virtual Function
+-------------------------
+Adaptive Virtual Function (AVF) allows the virtual function driver, or VF, to
+adapt to changing feature sets of the physical function driver (PF) with which
+it is associated. This allows system administrators to update a PF without
+having to update all the VFs associated with it. All AVFs have a single common
+device ID and branding string.
+
+AVFs have a minimum set of features known as "base mode," but may provide
+additional features depending on what features are available in the PF with
+which the AVF is associated. The following are base mode features:
+
+- 4 Queue Pairs (QP) and associated Configuration Status Registers (CSRs)
+  for Tx/Rx.
+- i40e descriptors and ring format.
+- Descriptor write-back completion.
+- 1 control queue, with i40e descriptors, CSRs and ring format.
+- 5 MSI-X interrupt vectors and corresponding i40e CSRs.
+- 1 Interrupt Throttle Rate (ITR) index.
+- 1 Virtual Station Interface (VSI) per VF.
+- 1 Traffic Class (TC), TC0
+- Receive Side Scaling (RSS) with 64 entry indirection table and key,
+  configured through the PF.
+- 1 unicast MAC address reserved per VF.
+- 16 MAC address filters for each VF.
+- Stateless offloads - non-tunneled checksums.
+- AVF device ID.
+- HW mailbox is used for VF to PF communications (including on Windows).
+
+IEEE 802.1ad (QinQ) Support
+---------------------------
+The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
+IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
+"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
+allow L2 tunneling and the ability to segregate traffic within a particular
+VLAN ID, among other uses.
+
+The following are examples of how to configure 802.1ad (QinQ)::
+
+  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
+  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
+
+Where "24" and "371" are example VLAN IDs.
+
+NOTES:
+  Receive checksum offloads, cloud filters, and VLAN acceleration are not
+  supported for 802.1ad (QinQ) packets.
+
+Application Device Queues (ADq)
+-------------------------------
+Application Device Queues (ADq) allows you to dedicate one or more queues to a
+specific application. This can reduce latency for the specified application,
+and allow Tx traffic to be rate limited per application. Follow the steps below
+to set ADq.
+
+1. Create traffic classes (TCs). Maximum of 8 TCs can be created per interface.
+The shaper bw_rlimit parameter is optional.
+
+Example: Sets up two tcs, tc0 and tc1, with 16 queues each and max tx rate set
+to 1Gbit for tc0 and 3Gbit for tc1.
+
+::
+
+  # tc qdisc add dev <interface> root mqprio num_tc 2 map 0 0 0 0 1 1 1 1
+  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
+  max_rate 1Gbit 3Gbit
+
+map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1
+sets priorities 0-3 to use tc0 and 4-7 to use tc1)
+
+queues: for each tc, <num queues>@<offset> (e.g. queues 16@0 16@16 assigns
+16 queues to tc0 at offset 0 and 16 queues to tc1 at offset 16. Max total
+number of queues for all tcs is 64 or number of cores, whichever is lower.)
+
+hw 1 mode channel: ‘channel’ with ‘hw’ set to 1 is a new new hardware
+offload mode in mqprio that makes full use of the mqprio options, the
+TCs, the queue configurations, and the QoS parameters.
+
+shaper bw_rlimit: for each tc, sets minimum and maximum bandwidth rates.
+Totals must be equal or less than port speed.
+
+For example: min_rate 1Gbit 3Gbit: Verify bandwidth limit using network
+monitoring tools such as ifstat or sar –n DEV [interval] [number of samples]
+
+2. Enable HW TC offload on interface::
+
+    # ethtool -K <interface> hw-tc-offload on
+
+3. Apply TCs to ingress (RX) flow of interface::
+
+    # tc qdisc add dev <interface> ingress
+
+NOTES:
+ - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
+ - ADq is not compatible with cloud filters.
+ - Setting up channels via ethtool (ethtool -L) is not supported when the TCs
+   are configured using mqprio.
+ - You must have iproute2 latest version
+ - NVM version 6.01 or later is required.
+ - ADq cannot be enabled when any the following features are enabled: Data
+   Center Bridging (DCB), Multiple Functions per Port (MFP), or Sideband Filters.
+ - If another driver (for example, DPDK) has set cloud filters, you cannot
+   enable ADq.
+ - Tunnel filters are not supported in ADq. If encapsulated packets do arrive
+   in non-tunnel mode, filtering will be done on the inner headers.  For example,
+   for VXLAN traffic in non-tunnel mode, PCTYPE is identified as a VXLAN
+   encapsulated packet, outer headers are ignored. Therefore, inner headers are
+   matched.
+ - If a TC filter on a PF matches traffic over a VF (on the PF), that traffic
+   will be routed to the appropriate queue of the PF, and will not be passed on
+   the VF. Such traffic will end up getting dropped higher up in the TCP/IP
+   stack as it does not match PF address data.
+ - If traffic matches multiple TC filters that point to different TCs, that
+   traffic will be duplicated and sent to all matching TC queues.  The hardware
+   switch mirrors the packet to a VSI list when multiple filters are matched.
+
+
+Known Issues/Troubleshooting
+============================
+
+Traffic Is Not Being Passed Between VM and Client
+-------------------------------------------------
+You may not be able to pass traffic between a client system and a
+Virtual Machine (VM) running on a separate host if the Virtual Function
+(VF, or Virtual NIC) is not in trusted mode and spoof checking is enabled
+on the VF. Note that this situation can occur in any combination of client,
+host, and guest operating system. For information on how to set the VF to
+trusted mode, refer to the section "VLAN Tag Packet Steering" in this
+readme document. For information on setting spoof checking, refer to the
+section "MAC and VLAN anti-spoofing feature" in this readme document.
+
+Do not unload port driver if VF with active VM is bound to it
+-------------------------------------------------------------
+Do not unload a port's driver if a Virtual Function (VF) with an active Virtual
+Machine (VM) is bound to it. Doing so will cause the port to appear to hang.
+Once the VM shuts down, or otherwise releases the VF, the command will complete.
+
+Virtual machine does not get link
+---------------------------------
+If the virtual machine has more than one virtual port assigned to it, and those
+virtual ports are bound to different physical ports, you may not get link on
+all of the virtual ports. The following command may work around the issue::
+
+  ethtool -r <PF>
+
+Where <PF> is the PF interface in the host, for example: p5p1. You may need to
+run the command more than once to get link on all virtual ports.
+
+MAC address of Virtual Function changes unexpectedly
+----------------------------------------------------
+If a Virtual Function's MAC address is not assigned in the host, then the VF
+(virtual function) driver will use a random MAC address. This random MAC
+address may change each time the VF driver is reloaded. You can assign a static
+MAC address in the host machine. This static MAC address will survive
+a VF driver reload.
+
+Driver Buffer Overflow Fix
+--------------------------
+The fix to resolve CVE-2016-8105, referenced in Intel SA-00069
+https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00069.html
+is included in this and future versions of the driver.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have one system
+on two IP networks in the same Ethernet broadcast domain (non-partitioned
+switch) behave as expected. All Ethernet interfaces will respond to IP traffic
+for any IP address assigned to the system. This results in unbalanced receive
+traffic.
+
+If you have multiple interfaces in a server, either turn on ARP filtering by
+entering::
+
+  echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+NOTE: This setting is not saved across reboots. The configuration change can be
+made permanent by adding the following line to the file /etc/sysctl.conf::
+
+  net.ipv4.conf.all.arp_filter = 1
+
+Another alternative is to install the interfaces in separate broadcast domains
+(either in different switches or in a switch partitioned to VLANs).
+
+Rx Page Allocation Errors
+-------------------------
+'Page allocation failure. order:0' errors may occur under stress.
+This is caused by the way the Linux kernel reports this stressed condition.

-Linux* Base Driver for Intel(R) Ethernet Adaptive Virtual Function
-==================================================================
-
-Intel Ethernet Adaptive Virtual Function Linux driver.
-Copyright(c) 2013-2018 Intel Corporation.
-
-Contents
-========
-
-- Identifying Your Adapter
-- Additional Configurations
-- Known Issues/Troubleshooting
-- Support
-
-This file describes the iavf Linux* Base Driver. This driver was formerly
-called i40evf.
-
-The iavf driver supports the below mentioned virtual function devices and
-can only be activated on kernels running the i40e or newer Physical Function
-(PF) driver compiled with CONFIG_PCI_IOV.  The iavf driver requires
-CONFIG_PCI_MSI to be enabled.
-
-The guest OS loading the iavf driver must support MSI-X interrupts.
-
-Identifying Your Adapter
-========================
-The driver in this kernel is compatible with devices based on the following:
- * Intel(R) XL710 X710 Virtual Function
- * Intel(R) X722 Virtual Function
- * Intel(R) XXV710 Virtual Function
- * Intel(R) Ethernet Adaptive Virtual Function
-
-For the best performance, make sure the latest NVM/FW is installed on your
-device.
-
-For information on how to identify your adapter, and for the latest NVM/FW
-images and Intel network drivers, refer to the Intel Support website:
-http://www.intel.com/support
-
-
-Additional Features and Configurations
-======================================
-
-Viewing Link Messages
----------------------
-Link messages will not be displayed to the console if the distribution is
-restricting system messages. In order to see network driver link messages on
-your console, set dmesg to eight by entering the following::
-
-  dmesg -n 8
-
-NOTE: This setting is not saved across reboots.
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-https://www.kernel.org/pub/software/network/ethtool/
-
-Setting VLAN Tag Stripping
---------------------------
-If you have applications that require Virtual Functions (VFs) to receive
-packets with VLAN tags, you can disable VLAN tag stripping for the VF. The
-Physical Function (PF) processes requests issued from the VF to enable or
-disable VLAN tag stripping. Note that if the PF has assigned a VLAN to a VF,
-then requests from that VF to set VLAN tag stripping will be ignored.
-
-To enable/disable VLAN tag stripping for a VF, issue the following command
-from inside the VM in which you are running the VF::
-
-  ethtool -K <if_name> rxvlan on/off
-
-or alternatively::
-
-  ethtool --offload <if_name> rxvlan on/off
-
-Adaptive Virtual Function
--------------------------
-Adaptive Virtual Function (AVF) allows the virtual function driver, or VF, to
-adapt to changing feature sets of the physical function driver (PF) with which
-it is associated. This allows system administrators to update a PF without
-having to update all the VFs associated with it. All AVFs have a single common
-device ID and branding string.
-
-AVFs have a minimum set of features known as "base mode," but may provide
-additional features depending on what features are available in the PF with
-which the AVF is associated. The following are base mode features:
-
-- 4 Queue Pairs (QP) and associated Configuration Status Registers (CSRs)
-  for Tx/Rx.
-- i40e descriptors and ring format.
-- Descriptor write-back completion.
-- 1 control queue, with i40e descriptors, CSRs and ring format.
-- 5 MSI-X interrupt vectors and corresponding i40e CSRs.
-- 1 Interrupt Throttle Rate (ITR) index.
-- 1 Virtual Station Interface (VSI) per VF.
-- 1 Traffic Class (TC), TC0
-- Receive Side Scaling (RSS) with 64 entry indirection table and key,
-  configured through the PF.
-- 1 unicast MAC address reserved per VF.
-- 16 MAC address filters for each VF.
-- Stateless offloads - non-tunneled checksums.
-- AVF device ID.
-- HW mailbox is used for VF to PF communications (including on Windows).
-
-IEEE 802.1ad (QinQ) Support
----------------------------
-The IEEE 802.1ad standard, informally known as QinQ, allows for multiple VLAN
-IDs within a single Ethernet frame. VLAN IDs are sometimes referred to as
-"tags," and multiple VLAN IDs are thus referred to as a "tag stack." Tag stacks
-allow L2 tunneling and the ability to segregate traffic within a particular
-VLAN ID, among other uses.
-
-The following are examples of how to configure 802.1ad (QinQ)::
-
-  ip link add link eth0 eth0.24 type vlan proto 802.1ad id 24
-  ip link add link eth0.24 eth0.24.371 type vlan proto 802.1Q id 371
-
-Where "24" and "371" are example VLAN IDs.
-
-NOTES:
-  Receive checksum offloads, cloud filters, and VLAN acceleration are not
-  supported for 802.1ad (QinQ) packets.
-
-Application Device Queues (ADq)
--------------------------------
-Application Device Queues (ADq) allows you to dedicate one or more queues to a
-specific application. This can reduce latency for the specified application,
-and allow Tx traffic to be rate limited per application. Follow the steps below
-to set ADq.

-  queues 16@0 16@16 hw 1 mode channel shaper bw_rlimit min_rate 1Gbit 2Gbit
-  max_rate 1Gbit 3Gbit
-
-map: priority mapping for up to 16 priorities to tcs (e.g. map 0 0 0 0 1 1 1 1

-
-3. Apply TCs to ingress (RX) flow of interface::
-
-    # tc qdisc add dev <interface> ingress
-
-NOTES:
- - Run all tc commands from the iproute2 <pathtoiproute2>/tc/ directory.
- - ADq is not compatible with cloud filters.
- - Setting up channels via ethtool (ethtool -L) is not supported when the TCs
-   are configured using mqprio.

+
+Identifying Your Adapter
+========================
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+http://www.intel.com/support
+
+
+Command Line Parameters
+========================
+If the driver is built as a module, the following optional parameters are used
+by entering them on the command line with the modprobe command using this
+syntax::
+
+    modprobe igb [<option>=<VAL1>,<VAL2>,...]
+
+There needs to be a <VAL#> for each network port in the system supported by
+this driver. The values will be applied to each instance, in function order.
+For example::
+
+    modprobe igb max_vfs=2,4
+
+In this case, there are two network ports supported by igb in the system.
+
+NOTE: A descriptor describes a data buffer and attributes related to the data
+buffer. This information is accessed by the hardware.
+
+max_vfs
+-------
+:Valid Range: 0-7
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions.  If the value is greater than 0 it will
+also force the VMDq parameter to be 1 or more.
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+    modprobe igb max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+    modprobe igb max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example::
+
+    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
+    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
+    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level debug messages displayed in the system logs.
+
+
+Additional Features and Configurations
+======================================
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+    ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+    ip link set mtu 9000 dev eth<x>
+    ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file:
+
+- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
+- For SLES: /etc/sysconfig/network/<config_file>
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9216. This value coincides
+with the maximum Jumbo Frames size of 9234 bytes.
+
+NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
+poor performance or loss of link.
+
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+
+https://www.kernel.org/pub/software/network/ethtool/
+
+
+Enabling Wake on LAN* (WoL)
+---------------------------
+WoL is configured through the ethtool* utility.
+
+WoL will be enabled on the system during the next shut down or reboot. For
+this driver version, in order to enable WoL, the igb driver must be loaded
+prior to shutting down or suspending the system.
+
+NOTE: Wake on LAN is only supported on port A of multi-port devices.  Also
+Wake On LAN is not supported for the following device:
+- Intel(R) Gigabit VT Quad Port Server Adapter
+
+
+Multiqueue
+----------
+In this mode, a separate MSI-X vector is allocated for each queue and one for
+"other" interrupts such as link status change and errors. All interrupts are
+throttled via interrupt moderation. Interrupt moderation must be used to avoid
+interrupt storms while the driver is processing one interrupt. The moderation
+value should be at least as large as the expected time for the driver to
+process an interrupt. Multiqueue is off by default.
+
+REQUIREMENTS: MSI-X support is required for Multiqueue. If MSI-X is not found,
+the system will fallback to MSI or to Legacy interrupts. This driver supports
+receive multiqueue on all kernels that support MSI-X.
+
+NOTE: On some kernels a reboot is required to switch between single queue mode
+and multiqueue mode or vice-versa.
+
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command):
+Spoof event(s) detected on VF(n), where n = the VF that attempted to do the
+spoofing
+
+
+Setting MAC Address, VLAN and Rate Limit Using IProute2 Tool
+------------------------------------------------------------
+You can set a MAC address of a Virtual Function (VF), a default VLAN and the
+rate limit using the IProute2 tool. Download the latest version of the
+IProute2 tool from Sourceforge if your version does not have all the features
+you require.

-Identifying Your Adapter
-========================
-For information on how to identify your adapter, and for the latest Intel
-network drivers, refer to the Intel Support website:
-http://www.intel.com/support
-
-
-Command Line Parameters
-========================
-If the driver is built as a module, the following optional parameters are used
-by entering them on the command line with the modprobe command using this
-syntax::
-
-    modprobe igb [<option>=<VAL1>,<VAL2>,...]
-
-There needs to be a <VAL#> for each network port in the system supported by
-this driver. The values will be applied to each instance, in function order.
-For example::
-
-    modprobe igb max_vfs=2,4
-
-In this case, there are two network ports supported by igb in the system.
-
-NOTE: A descriptor describes a data buffer and attributes related to the data
-buffer. This information is accessed by the hardware.
-
-max_vfs
--------
-:Valid Range: 0-7
-
-This parameter adds support for SR-IOV. It causes the driver to spawn up to
-max_vfs worth of virtual functions.  If the value is greater than 0 it will
-also force the VMDq parameter to be 1 or more.
-
-The parameters for the driver are referenced by position. Thus, if you have a
-dual port adapter, or more than one adapter in your system, and want N virtual
-functions per port, you must specify a number for each port with each parameter
-separated by a comma. For example::
-
-    modprobe igb max_vfs=4
-
-This will spawn 4 VFs on the first port.
-
-::
-
-    modprobe igb max_vfs=2,4
-
-This will spawn 2 VFs on the first port and 4 VFs on the second port.
-
-NOTE: Caution must be used in loading the driver with these parameters.
-Depending on your system configuration, number of slots, etc., it is impossible
-to predict in all cases where the positions would be on the command line.
-
-NOTE: Neither the device nor the driver control how VFs are mapped into config
-space. Bus layout will vary by operating system. On operating systems that
-support it, you can check sysfs to find the mapping.
-
-NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
-and VLAN tag stripping/insertion will remain enabled. Please remove the old
-VLAN filter before the new VLAN filter is added. For example::
-
-    ip link set eth0 vf 0 vlan 100	// set vlan 100 for VF 0
-    ip link set eth0 vf 0 vlan 0	// Delete vlan 100
-    ip link set eth0 vf 0 vlan 200	// set a new vlan 200 for VF 0
-
-Debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-This parameter adjusts the level debug messages displayed in the system logs.
-
-
-Additional Features and Configurations
-======================================
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-    ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-    ip link set mtu 9000 dev eth<x>
-    ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file:
-
-- For RHEL: /etc/sysconfig/network-scripts/ifcfg-eth<x>
-- For SLES: /etc/sysconfig/network/<config_file>
-
-NOTE: The maximum MTU setting for Jumbo Frames is 9216. This value coincides
-with the maximum Jumbo Frames size of 9234 bytes.
-
-NOTE: Using Jumbo frames at 10 or 100 Mbps is not supported and may result in
-poor performance or loss of link.
-
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-
-https://www.kernel.org/pub/software/network/ethtool/

----------------------------
-WoL is configured through the ethtool* utility.
-
-WoL will be enabled on the system during the next shut down or reboot. For
-this driver version, in order to enable WoL, the igb driver must be loaded
-prior to shutting down or suspending the system.
-
-NOTE: Wake on LAN is only supported on port A of multi-port devices.  Also
-Wake On LAN is not supported for the following device:

+In This Release
+===============
+
+This file describes the ixgb Linux Base Driver for the 10 Gigabit Intel(R)
+Network Connection.  This driver includes support for Itanium(R)2-based
+systems.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your 10 Gigabit adapter.  All hardware requirements listed apply
+to use with Linux.
+
+The following features are available in this kernel:
+ - Native VLANs
+ - Channel Bonding (teaming)
+ - SNMP
+
+Channel Bonding documentation can be found in the Linux kernel source:
+/Documentation/networking/bonding.txt
+
+The driver information previously displayed in the /proc filesystem is not
+supported in this release.  Alternatively, you can use ethtool (version 1.6
+or later), lspci, and iproute2 to obtain the same information.
+
+Instructions on updating ethtool can be found in the section "Additional
+Configurations" later in this document.
+
+
+Identifying Your Adapter
+========================
+
+The following Intel network adapters are compatible with the drivers in this
+release:
+
++------------+------------------------------+----------------------------------+
+| Controller | Adapter Name                 | Physical Layer                   |
++============+==============================+==================================+
+| 82597EX    | Intel(R) PRO/10GbE LR/SR/CX4 | - 10G Base-LR (fiber)            |
+|            | Server Adapters              | - 10G Base-SR (fiber)            |
+|            |                              | - 10G Base-CX4 (copper)          |
++------------+------------------------------+----------------------------------+
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+    https://support.intel.com
+
+
+Command Line Parameters
+=======================
+
+If the driver is built as a module, the  following optional parameters are
+used by entering them on the command line with the modprobe command using
+this syntax::
+
+    modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
+
+For example, with two 10GbE PCI adapters, entering::
+
+    modprobe ixgb TxDescriptors=80,128
+
+loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
+resources for the second adapter.
+
+The default value for each parameter is generally the recommended setting,
+unless otherwise noted.
+
+Copybreak
+---------
+:Valid Range: 0-XXXX
+:Default Value: 256
+
+    This is the maximum size of packet that is copied to a new buffer on
+    receive.
+
+Debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+    This parameter adjusts the level of debug messages displayed in the
+    system logs.
+
+FlowControl
+-----------
+:Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
+:Default Value: 1 if no EEPROM, otherwise read from EEPROM
+
+    This parameter controls the automatic generation(Tx) and response(Rx) to
+    Ethernet PAUSE frames.  There are hardware bugs associated with enabling
+    Tx flow control so beware.
+
+RxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 1024
+
+    This value is the number of receive descriptors allocated by the driver.
+    Increasing this value allows the driver to buffer more incoming packets.
+    Each descriptor is 16 bytes.  A receive buffer is also allocated for
+    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
+    depending on the MTU setting.  When the MTU size is 1500 or less, the
+    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
+    receive buffer size will be either 4056, 8192, or 16384 bytes.  The
+    maximum MTU size is 16114.
+
+TxDescriptors
+-------------
+:Valid Range: 64-4096
+:Default Value: 256
+
+    This value is the number of transmit descriptors allocated by the driver.
+    Increasing this value allows the driver to queue more transmits.  Each
+    descriptor is 16 bytes.
+
+RxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 72
+
+    This value delays the generation of receive interrupts in units of
+    0.8192 microseconds.  Receive interrupt reduction can improve CPU
+    efficiency if properly tuned for specific network traffic.  Increasing
+    this value adds extra latency to frame reception and can end up
+    decreasing the throughput of TCP traffic.  If the system is reporting
+    dropped receives, this value may be set too high, causing the driver to
+    run out of available receive descriptors.
+
+TxIntDelay
+----------
+:Valid Range: 0-65535 (0=off)
+:Default Value: 32
+
+    This value delays the generation of transmit interrupts in units of
+    0.8192 microseconds.  Transmit interrupt reduction can improve CPU
+    efficiency if properly tuned for specific network traffic.  Increasing
+    this value adds extra latency to frame transmission and can end up
+    decreasing the throughput of TCP traffic.  If this value is set too high,
+    it will cause the driver to run out of available transmit descriptors.
+
+XsumRX
+------
+:Valid Range: 0-1
+:Default Value: 1
+
+    A value of '1' indicates that the driver should enable IP checksum
+    offload for received packets (both UDP and TCP) to the adapter hardware.
+
+RxFCHighThresh
+--------------
+:Valid Range: 1,536-262,136 (0x600 - 0x3FFF8, 8 byte granularity)
+:Default Value: 196,608 (0x30000)
+
+    Receive Flow control high threshold (when we send a pause frame)
+
+RxFCLowThresh
+-------------
+:Valid Range: 64-262,136 (0x40 - 0x3FFF8, 8 byte granularity)
+:Default Value: 163,840 (0x28000)
+
+    Receive Flow control low threshold (when we send a resume frame)
+
+FCReqTimeout
+------------
+:Valid Range: 1-65535
+:Default Value: 65535
+
+    Flow control request timeout (how long to pause the link partner's tx)
+
+IntDelayEnable
+--------------
+:Value Range: 0,1
+:Default Value: 1
+
+    Interrupt Delay, 0 disables transmit interrupt delay and 1 enables it.
+
+
+Improving Performance
+=====================
+
+With the 10 Gigabit server adapters, the default Linux configuration will
+very likely limit the total available throughput artificially.  There is a set
+of configuration changes that, when applied together, will increase the ability
+of Linux to transmit and receive data.  The following enhancements were
+originally acquired from settings published at http://www.spec.org/web99/ for
+various submitted results using Linux.
+
+NOTE:
+  These changes are only suggestions, and serve as a starting point for
+  tuning your network performance.
+
+The changes are made in three major ways, listed in order of greatest effect:
+
+- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
+  parameter.
+- Use sysctl to modify /proc parameters (essentially kernel tuning)
+- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
+  transmit burst lengths on the bus.
+
+NOTE:
+  setpci modifies the adapter's configuration registers to allow it to read
+  up to 4k bytes at a time (for transmits).  However, for some systems the
+  behavior after modifying this register may be undefined (possibly errors of
+  some kind).  A power-cycle, hard reset or explicitly setting the e6 register
+  back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
+  stable configuration.
+
+- COPY these lines and paste them into ixgb_perf.sh:
+
+::
+
+  #!/bin/bash
+  echo "configuring network performance , edit this file to change the interface
+  or device ID of 10GbE card"
+  # set mmrbc to 4k reads, modify only Intel 10GbE device IDs
+  # replace 1a48 with appropriate 10GbE device's ID installed on the system,
+  # if needed.
+  setpci -d 8086:1a48 e6.b=2e
+  # set the MTU (max transmission unit) - it requires your switch and clients
+  # to change as well.
+  # set the txqueuelen
+  # your ixgb adapter should be loaded as eth1 for this to work, change if needed
+  ip li set dev eth1 mtu 9000 txqueuelen 1000 up
+  # call the sysctl utility to modify /proc/sys entries
+  sysctl -p ./sysctl_ixgb.conf
+
+- COPY these lines and paste them into sysctl_ixgb.conf:
+
+::
+
+  # some of the defaults may be different for your kernel
+  # call this file with sysctl -p <this file>
+  # these are just suggested values that worked well to increase throughput in
+  # several network benchmark tests, your mileage may vary
+
+  ### IPV4 specific settings
+  # turn TCP timestamp support off, default 1, reduces CPU use
+  net.ipv4.tcp_timestamps = 0
+  # turn SACK support off, default on
+  # on systems with a VERY fast bus -> memory interface this is the big gainer
+  net.ipv4.tcp_sack = 0
+  # set min/default/max TCP read buffer, default 4096 87380 174760
+  net.ipv4.tcp_rmem = 10000000 10000000 10000000

+  # set number of unprocessed input packets before kernel starts dropping them; default 300
+  net.core.netdev_max_backlog = 300000
+
+Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
+your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
+ID installed on the system.
+
+NOTE:
+  Unless these scripts are added to the boot process, these changes will
+  only last only until the next system reboot.
+
+
+Resolving Slow UDP Traffic
+--------------------------
+If your server does not seem to be able to receive UDP traffic as fast as it
+can receive TCP traffic, it could be because Linux, by default, does not set
+the network stack buffers as large as they need to be to support high UDP
+transfer rates.  One way to alleviate this problem is to allow more memory to
+be used by the IP stack to store incoming data.
+
+For instance, use the commands::
+
+    sysctl -w net.core.rmem_max=262143
+
+and::
+
+    sysctl -w net.core.rmem_default=262143
+
+to increase the read buffer memory max and default to 262143 (256k - 1) from
+defaults of max=131071 (128k - 1) and default=65535 (64k - 1).  These variables
+will increase the amount of memory used by the network stack for receives, and
+can be increased significantly more if necessary for your application.
+
+
+Additional Configurations
+=========================
+
+Configuring the Driver on Different Distributions
+-------------------------------------------------
+Configuring a network driver to load properly when the system is started is
+distribution dependent. Typically, the configuration process involves adding
+an alias line to /etc/modprobe.conf as well as editing other system startup
+scripts and/or configuration files.  Many popular Linux distributions ship
+with tools to make these changes for you.  To learn the proper way to
+configure a network device for your system, refer to your distribution
+documentation.  If during this process you are asked for the driver or module
+name, the name for the Linux Base Driver for the Intel 10GbE Family of
+Adapters is ixgb.
+
+Viewing Link Messages
+---------------------
+Link messages will not be displayed to the console if the distribution is
+restricting system messages. In order to see network driver link messages on
+your console, set dmesg to eight by entering the following::
+
+    dmesg -n 8
+
+NOTE: This setting is not saved across reboots.
+
+Jumbo Frames
+------------
+The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
+enabled by changing the MTU to a value larger than the default of 1500.
+The maximum value for the MTU is 16114.  Use the ip command to
+increase the MTU size.  For example::
+
+    ip li set dev ethx mtu 9000
+
+The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
+with the maximum Jumbo Frames size of 16128.
+
+Ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information.  The ethtool
+version 1.6 or later is required for this functionality.
+
+The latest release of ethtool can be found from
+https://www.kernel.org/pub/software/network/ethtool/
+
+NOTE:
+  The ethtool version 1.6 only supports a limited set of ethtool options.
+  Support for a more complete ethtool feature set can be enabled by
+  upgrading to the latest version.
+
+NAPI
+----
+NAPI (Rx polling mode) is supported in the ixgb driver.
+
+See https://wiki.linuxfoundation.org/networking/napi for more information on
+NAPI.
+
+
+Known Issues/Troubleshooting
+============================
+
+NOTE:
+  After installing the driver, if your Intel Network Connection is not
+  working, verify in the "In This Release" section of the readme that you have
+  installed the correct driver.
+
+Cable Interoperability Issue with Fujitsu XENPAK Module in SmartBits Chassis
+----------------------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
+Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
+chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
+The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
+Server adapter or the SmartBits. If this situation occurs using a different
+cable assembly may resolve the issue.
+
+Cable Interoperability Issues with HP Procurve 3400cl Switch Port
+-----------------------------------------------------------------
+Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
+adapter is connected to an HP Procurve 3400cl switch port using short cables
+(1 m or shorter). If this situation occurs, using a longer cable may resolve
+the issue.
+
+Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
+Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
+errors may be received either by the CX4 Server adapter or at the switch. If
+this situation occurs, using a different cable assembly may resolve the issue.
+
+Jumbo Frames System Requirement
+-------------------------------
+Memory allocation failures have been observed on Linux systems with 64 MB
+of RAM or less that are running Jumbo Frames.  If you are using Jumbo
+Frames, your system may require more than the advertised minimum
+requirement of 64 MB of system memory.
+
+Performance Degradation with Jumbo Frames
+-----------------------------------------
+Degradation in throughput performance may be observed in some Jumbo frames
+environments.  If this is observed, increasing the application's socket buffer
+size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
+See the specific application manual and /usr/src/linux*/Documentation/
+networking/ip-sysctl.txt for more details.
+
+Allocating Rx Buffers when Using Jumbo Frames
+---------------------------------------------
+Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
+the available memory is heavily fragmented. This issue may be seen with PCI-X
+adapters or with packet split disabled. This can be reduced or eliminated
+by changing the amount of available memory for receive buffer allocation, by
+increasing /proc/sys/vm/min_free_kbytes.
+
+Multiple Interfaces on Same Ethernet Broadcast Network
+------------------------------------------------------
+Due to the default ARP behavior on Linux, it is not possible to have
+one system on two IP networks in the same Ethernet broadcast domain
+(non-partitioned switch) behave as expected.  All Ethernet interfaces
+will respond to IP traffic for any IP address assigned to the system.
+This results in unbalanced receive traffic.
+
+If you have multiple interfaces in a server, do either of the following:
+
+  - Turn on ARP filtering by entering::
+
+      echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
+
+  - Install the interfaces in separate broadcast domains - either in
+    different switches or in a switch partitioned to VLANs.
+
+UDP Stress Test Dropped Packet Issue
+--------------------------------------
+Under small packets UDP stress test with 10GbE driver, the Linux system
+may drop UDP packets due to the fullness of socket buffers. You may want
+to change the driver's Flow Control variables to the minimum value for
+controlling packet reception.
+
+Tx Hangs Possible Under Stress
+------------------------------
+Under stress conditions, if TX hangs occur, turning off TSO
+"ethtool -K eth0 tso off" may resolve the problem.

-
-For more information on how to identify your adapter, go to the Adapter &
-Driver ID Guide at:
-
-    https://support.intel.com
-
-
-Command Line Parameters
-=======================
-
-If the driver is built as a module, the  following optional parameters are
-used by entering them on the command line with the modprobe command using
-this syntax::
-
-    modprobe ixgb [<option>=<VAL1>,<VAL2>,...]
-
-For example, with two 10GbE PCI adapters, entering::
-
-    modprobe ixgb TxDescriptors=80,128
-
-loads the ixgb driver with 80 TX resources for the first adapter and 128 TX
-resources for the second adapter.
-
-The default value for each parameter is generally the recommended setting,
-unless otherwise noted.
-
-Copybreak
----------
-:Valid Range: 0-XXXX
-:Default Value: 256
-
-    This is the maximum size of packet that is copied to a new buffer on
-    receive.
-
-Debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-    This parameter adjusts the level of debug messages displayed in the
-    system logs.
-
-FlowControl
------------
-:Valid Range: 0-3 (0=none, 1=Rx only, 2=Tx only, 3=Rx&Tx)
-:Default Value: 1 if no EEPROM, otherwise read from EEPROM
-
-    This parameter controls the automatic generation(Tx) and response(Rx) to
-    Ethernet PAUSE frames.  There are hardware bugs associated with enabling
-    Tx flow control so beware.
-
-RxDescriptors
--------------
-:Valid Range: 64-4096
-:Default Value: 1024
-
-    This value is the number of receive descriptors allocated by the driver.
-    Increasing this value allows the driver to buffer more incoming packets.
-    Each descriptor is 16 bytes.  A receive buffer is also allocated for
-    each descriptor and can be either 2048, 4056, 8192, or 16384 bytes,
-    depending on the MTU setting.  When the MTU size is 1500 or less, the
-    receive buffer size is 2048 bytes. When the MTU is greater than 1500 the
-    receive buffer size will be either 4056, 8192, or 16384 bytes.  The
-    maximum MTU size is 16114.
-
-TxDescriptors
--------------
-:Valid Range: 64-4096
-:Default Value: 256
-
-    This value is the number of transmit descriptors allocated by the driver.
-    Increasing this value allows the driver to queue more transmits.  Each
-    descriptor is 16 bytes.
-
-RxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 72
-
-    This value delays the generation of receive interrupts in units of
-    0.8192 microseconds.  Receive interrupt reduction can improve CPU
-    efficiency if properly tuned for specific network traffic.  Increasing
-    this value adds extra latency to frame reception and can end up
-    decreasing the throughput of TCP traffic.  If the system is reporting
-    dropped receives, this value may be set too high, causing the driver to
-    run out of available receive descriptors.
-
-TxIntDelay
-----------
-:Valid Range: 0-65535 (0=off)
-:Default Value: 32
-
-    This value delays the generation of transmit interrupts in units of
-    0.8192 microseconds.  Transmit interrupt reduction can improve CPU
-    efficiency if properly tuned for specific network traffic.  Increasing
-    this value adds extra latency to frame transmission and can end up
-    decreasing the throughput of TCP traffic.  If this value is set too high,
-    it will cause the driver to run out of available transmit descriptors.
-
-XsumRX
-------
-:Valid Range: 0-1
-:Default Value: 1
-
-    A value of '1' indicates that the driver should enable IP checksum
-    offload for received packets (both UDP and TCP) to the adapter hardware.
-
-RxFCHighThresh
---------------
-:Valid Range: 1,536-262,136 (0x600 - 0x3FFF8, 8 byte granularity)
-:Default Value: 196,608 (0x30000)
-
-    Receive Flow control high threshold (when we send a pause frame)
-
-RxFCLowThresh
--------------
-:Valid Range: 64-262,136 (0x40 - 0x3FFF8, 8 byte granularity)
-:Default Value: 163,840 (0x28000)
-
-    Receive Flow control low threshold (when we send a resume frame)
-
-FCReqTimeout
-------------
-:Valid Range: 1-65535
-:Default Value: 65535
-
-    Flow control request timeout (how long to pause the link partner's tx)
-
-IntDelayEnable
---------------
-:Value Range: 0,1
-:Default Value: 1
-
-    Interrupt Delay, 0 disables transmit interrupt delay and 1 enables it.
-
-
-Improving Performance
-=====================
-
-With the 10 Gigabit server adapters, the default Linux configuration will
-very likely limit the total available throughput artificially.  There is a set
-of configuration changes that, when applied together, will increase the ability
-of Linux to transmit and receive data.  The following enhancements were
-originally acquired from settings published at http://www.spec.org/web99/ for
-various submitted results using Linux.
-
-NOTE:
-  These changes are only suggestions, and serve as a starting point for
-  tuning your network performance.
-
-The changes are made in three major ways, listed in order of greatest effect:
-
-- Use ip link to modify the mtu (maximum transmission unit) and the txqueuelen
-  parameter.
-- Use sysctl to modify /proc parameters (essentially kernel tuning)
-- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
-  transmit burst lengths on the bus.
-
-NOTE:
-  setpci modifies the adapter's configuration registers to allow it to read
-  up to 4k bytes at a time (for transmits).  However, for some systems the
-  behavior after modifying this register may be undefined (possibly errors of
-  some kind).  A power-cycle, hard reset or explicitly setting the e6 register
-  back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
-  stable configuration.
-
-- COPY these lines and paste them into ixgb_perf.sh:
-
-::
-
-  #!/bin/bash
-  echo "configuring network performance , edit this file to change the interface
-  or device ID of 10GbE card"
-  # set mmrbc to 4k reads, modify only Intel 10GbE device IDs
-  # replace 1a48 with appropriate 10GbE device's ID installed on the system,
-  # if needed.
-  setpci -d 8086:1a48 e6.b=2e
-  # set the MTU (max transmission unit) - it requires your switch and clients
-  # to change as well.
-  # set the txqueuelen
-  # your ixgb adapter should be loaded as eth1 for this to work, change if needed
-  ip li set dev eth1 mtu 9000 txqueuelen 1000 up
-  # call the sysctl utility to modify /proc/sys entries
-  sysctl -p ./sysctl_ixgb.conf
-
-- COPY these lines and paste them into sysctl_ixgb.conf:
-
-::
-
-  # some of the defaults may be different for your kernel
-  # call this file with sysctl -p <this file>
-  # these are just suggested values that worked well to increase throughput in
-  # several network benchmark tests, your mileage may vary
-
-  ### IPV4 specific settings
-  # turn TCP timestamp support off, default 1, reduces CPU use
-  net.ipv4.tcp_timestamps = 0
-  # turn SACK support off, default on
-  # on systems with a VERY fast bus -> memory interface this is the big gainer
-  net.ipv4.tcp_sack = 0
-  # set min/default/max TCP read buffer, default 4096 87380 174760
-  net.ipv4.tcp_rmem = 10000000 10000000 10000000
-  # set min/pressure/max TCP write buffer, default 4096 16384 131072
-  net.ipv4.tcp_wmem = 10000000 10000000 10000000
-  # set min/pressure/max TCP buffer space, default 31744 32256 32768
-  net.ipv4.tcp_mem = 10000000 10000000 10000000
-
-  ### CORE settings (mostly for socket and UDP effect)
-  # set maximum receive socket buffer size, default 131071
-  net.core.rmem_max = 524287
-  # set maximum send socket buffer size, default 131071
-  net.core.wmem_max = 524287
-  # set default receive socket buffer size, default 65535
-  net.core.rmem_default = 524287
-  # set default send socket buffer size, default 65535
-  net.core.wmem_default = 524287
-  # set maximum amount of option memory buffers, default 10240
-  net.core.optmem_max = 524287
-  # set number of unprocessed input packets before kernel starts dropping them; default 300
-  net.core.netdev_max_backlog = 300000
-
-Edit the ixgb_perf.sh script if necessary to change eth1 to whatever interface
-your ixgb driver is using and/or replace '1a48' with appropriate 10GbE device's
-ID installed on the system.
-
-NOTE:
-  Unless these scripts are added to the boot process, these changes will
-  only last only until the next system reboot.
-
-
-Resolving Slow UDP Traffic
---------------------------
-If your server does not seem to be able to receive UDP traffic as fast as it
-can receive TCP traffic, it could be because Linux, by default, does not set
-the network stack buffers as large as they need to be to support high UDP
-transfer rates.  One way to alleviate this problem is to allow more memory to
-be used by the IP stack to store incoming data.
-
-For instance, use the commands::
-
-    sysctl -w net.core.rmem_max=262143
-
-and::
-
-    sysctl -w net.core.rmem_default=262143
-
-to increase the read buffer memory max and default to 262143 (256k - 1) from
-defaults of max=131071 (128k - 1) and default=65535 (64k - 1).  These variables
-will increase the amount of memory used by the network stack for receives, and
-can be increased significantly more if necessary for your application.
-
-
-Additional Configurations
-=========================
-
-Configuring the Driver on Different Distributions
--------------------------------------------------
-Configuring a network driver to load properly when the system is started is
-distribution dependent. Typically, the configuration process involves adding
-an alias line to /etc/modprobe.conf as well as editing other system startup
-scripts and/or configuration files.  Many popular Linux distributions ship
-with tools to make these changes for you.  To learn the proper way to
-configure a network device for your system, refer to your distribution
-documentation.  If during this process you are asked for the driver or module
-name, the name for the Linux Base Driver for the Intel 10GbE Family of
-Adapters is ixgb.
-
-Viewing Link Messages
----------------------
-Link messages will not be displayed to the console if the distribution is
-restricting system messages. In order to see network driver link messages on
-your console, set dmesg to eight by entering the following::
-
-    dmesg -n 8
-
-NOTE: This setting is not saved across reboots.
-
-Jumbo Frames
-------------
-The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
-enabled by changing the MTU to a value larger than the default of 1500.
-The maximum value for the MTU is 16114.  Use the ip command to
-increase the MTU size.  For example::
-
-    ip li set dev ethx mtu 9000
-
-The maximum MTU setting for Jumbo Frames is 16114.  This value coincides
-with the maximum Jumbo Frames size of 16128.
-
-Ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information.  The ethtool
-version 1.6 or later is required for this functionality.
-
-The latest release of ethtool can be found from
-https://www.kernel.org/pub/software/network/ethtool/
-
-NOTE:
-  The ethtool version 1.6 only supports a limited set of ethtool options.
-  Support for a more complete ethtool feature set can be enabled by
-  upgrading to the latest version.
-
-NAPI
-----
-NAPI (Rx polling mode) is supported in the ixgb driver.
-
-See https://wiki.linuxfoundation.org/networking/napi for more information on
-NAPI.

-
-Known Issues/Troubleshooting
-============================
-
-NOTE:
-  After installing the driver, if your Intel Network Connection is not
-  working, verify in the "In This Release" section of the readme that you have
-  installed the correct driver.
-
-Cable Interoperability Issue with Fujitsu XENPAK Module in SmartBits Chassis
-----------------------------------------------------------------------------
-Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
-Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
-chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
-The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
-Server adapter or the SmartBits. If this situation occurs using a different
-cable assembly may resolve the issue.
-
-Cable Interoperability Issues with HP Procurve 3400cl Switch Port
------------------------------------------------------------------
-Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
-adapter is connected to an HP Procurve 3400cl switch port using short cables
-(1 m or shorter). If this situation occurs, using a longer cable may resolve
-the issue.
-
-Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
-Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
-errors may be received either by the CX4 Server adapter or at the switch. If
-this situation occurs, using a different cable assembly may resolve the issue.
-
-Jumbo Frames System Requirement
--------------------------------
-Memory allocation failures have been observed on Linux systems with 64 MB
-of RAM or less that are running Jumbo Frames.  If you are using Jumbo
-Frames, your system may require more than the advertised minimum
-requirement of 64 MB of system memory.
-
-Performance Degradation with Jumbo Frames
------------------------------------------
-Degradation in throughput performance may be observed in some Jumbo frames
-environments.  If this is observed, increasing the application's socket buffer
-size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
-See the specific application manual and /usr/src/linux*/Documentation/

-UDP Stress Test Dropped Packet Issue
---------------------------------------
-Under small packets UDP stress test with 10GbE driver, the Linux system
-may drop UDP packets due to the fullness of socket buffers. You may want
-to change the driver's Flow Control variables to the minimum value for
-controlling packet reception.
-
-Tx Hangs Possible Under Stress
-------------------------------
-Under stress conditions, if TX hangs occur, turning off TSO
-"ethtool -K eth0 tso off" may resolve the problem.

+
+Command Line Parameters
+=======================
+
+max_vfs
+-------
+:Valid Range: 1-63
+
+This parameter adds support for SR-IOV. It causes the driver to spawn up to
+max_vfs worth of virtual functions.
+If the value is greater than 0 it will also force the VMDq parameter to be 1 or
+more.
+
+NOTE: This parameter is only used on kernel 3.7.x and below. On kernel 3.8.x
+and above, use sysfs to enable VFs. Also, for Red Hat distributions, this
+parameter is only used on version 6.6 and older. For version 6.7 and newer, use
+sysfs. For example::
+
+  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs // enable VFs
+  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs               //disable VFs
+
+The parameters for the driver are referenced by position. Thus, if you have a
+dual port adapter, or more than one adapter in your system, and want N virtual
+functions per port, you must specify a number for each port with each parameter
+separated by a comma. For example::
+
+  modprobe ixgbe max_vfs=4
+
+This will spawn 4 VFs on the first port.
+
+::
+
+  modprobe ixgbe max_vfs=2,4
+
+This will spawn 2 VFs on the first port and 4 VFs on the second port.
+
+NOTE: Caution must be used in loading the driver with these parameters.
+Depending on your system configuration, number of slots, etc., it is impossible
+to predict in all cases where the positions would be on the command line.
+
+NOTE: Neither the device nor the driver control how VFs are mapped into config
+space. Bus layout will vary by operating system. On operating systems that
+support it, you can check sysfs to find the mapping.
+
+NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
+and VLAN tag stripping/insertion will remain enabled. Please remove the old
+VLAN filter before the new VLAN filter is added. For example,
+
+::
+
+  ip link set eth0 vf 0 vlan 100 // set VLAN 100 for VF 0
+  ip link set eth0 vf 0 vlan 0   // Delete VLAN 100
+  ip link set eth0 vf 0 vlan 200 // set a new VLAN 200 for VF 0
+
+With kernel 3.6, the driver supports the simultaneous usage of max_vfs and DCB
+features, subject to the constraints described below. Prior to kernel 3.6, the
+driver did not support the simultaneous operation of max_vfs greater than 0 and
+the DCB features (multiple traffic classes utilizing Priority Flow Control and
+Extended Transmission Selection).
+
+When DCB is enabled, network traffic is transmitted and received through
+multiple traffic classes (packet buffers in the NIC). The traffic is associated
+with a specific class based on priority, which has a value of 0 through 7 used
+in the VLAN tag. When SR-IOV is not enabled, each traffic class is associated
+with a set of receive/transmit descriptor queue pairs. The number of queue
+pairs for a given traffic class depends on the hardware configuration. When
+SR-IOV is enabled, the descriptor queue pairs are grouped into pools. The
+Physical Function (PF) and each Virtual Function (VF) is allocated a pool of
+receive/transmit descriptor queue pairs. When multiple traffic classes are
+configured (for example, DCB is enabled), each pool contains a queue pair from
+each traffic class. When a single traffic class is configured in the hardware,
+the pools contain multiple queue pairs from the single traffic class.
+
+The number of VFs that can be allocated depends on the number of traffic
+classes that can be enabled. The configurable number of traffic classes for
+each enabled VF is as follows:
+0 - 15 VFs = Up to 8 traffic classes, depending on device support
+16 - 31 VFs = Up to 4 traffic classes
+32 - 63 VFs = 1 traffic class
+
+When VFs are configured, the PF is allocated one pool as well. The PF supports
+the DCB features with the constraint that each traffic class will only use a
+single queue pair. When zero VFs are configured, the PF can support multiple
+queue pairs per traffic class.
+
+allow_unsupported_sfp
+---------------------
+:Valid Range: 0,1
+:Default Value: 0 (disabled)
+
+This parameter allows unsupported and untested SFP+ modules on 82599-based
+adapters, as long as the type of module is known to the driver.
+
+debug
+-----
+:Valid Range: 0-16 (0=none,...,16=all)
+:Default Value: 0
+
+This parameter adjusts the level of debug messages displayed in the system
+logs.
+
+
+Additional Features and Configurations
+======================================
+
+Flow Control
+------------
+Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
+receiving and transmitting pause frames for ixgbe. When transmit is enabled,
+pause frames are generated when the receive packet buffer crosses a predefined
+threshold. When receive is enabled, the transmit unit will halt for the time
+delay specified when a pause frame is received.
+
+NOTE: You must have a flow control capable link partner.
+
+Flow Control is enabled by default.
+
+Use ethtool to change the flow control settings. To enable or disable Rx or
+Tx Flow Control::
+
+  ethtool -A eth? rx <on|off> tx <on|off>
+
+Note: This command only enables or disables Flow Control if auto-negotiation is
+disabled. If auto-negotiation is enabled, this command changes the parameters
+used for auto-negotiation with the link partner.
+
+To enable or disable auto-negotiation::
+
+  ethtool -s eth? autoneg <on|off>
+
+Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
+on your device, you may not be able to change the auto-negotiation setting.
+
+NOTE: For 82598 backplane cards entering 1 gigabit mode, flow control default
+behavior is changed to off. Flow control in 1 gigabit mode on these devices can
+lead to transmit hangs.
+
+Intel(R) Ethernet Flow Director
+-------------------------------
+The Intel Ethernet Flow Director performs the following tasks:
+
+- Directs receive packets according to their flows to different queues.
+- Enables tight control on routing a flow in the platform.
+- Matches flows and CPU cores for flow affinity.
+- Supports multiple parameters for flexible flow classification and load
+  balancing (in SFP mode only).
+
+NOTE: Intel Ethernet Flow Director masking works in the opposite manner from
+subnet masking. In the following command::
+
+  #ethtool -N eth11 flow-type ip4 src-ip 172.4.1.2 m 255.0.0.0 dst-ip \
+  172.21.1.1 m 255.128.0.0 action 31
+
+The src-ip value that is written to the filter will be 0.4.1.2, not 172.0.0.0
+as might be expected. Similarly, the dst-ip value written to the filter will be
+0.21.1.1, not 172.0.0.0.
+
+To enable or disable the Intel Ethernet Flow Director::
+
+  # ethtool -K ethX ntuple <on|off>
+
+When disabling ntuple filters, all the user programmed filters are flushed from
+the driver cache and hardware. All needed filters must be re-added when ntuple
+is re-enabled.
+
+To add a filter that directs packet to queue 2, use -U or -N switch::
+
+  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
+  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
+
+To see the list of filters currently present::
+
+  # ethtool <-u|-n> ethX
+
+Sideband Perfect Filters
+------------------------
+Sideband Perfect Filters are used to direct traffic that matches specified
+characteristics. They are enabled through ethtool's ntuple interface. To add a
+new filter use the following command::
+
+  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
+  dst-port <port> action <queue>
+
+Where:
+  <device> - the ethernet device to program
+  <type> - can be ip4, tcp4, udp4, or sctp4
+  <ip> - the IP address to match on
+  <port> - the port number to match on
+  <queue> - the queue to direct traffic towards (-1 discards the matched traffic)
+
+Use the following command to delete a filter::
+
+  ethtool -U <device> delete <N>
+
+Where <N> is the filter id displayed when printing all the active filters, and
+may also have been specified using "loc <N>" when adding the filter.
+
+The following example matches TCP traffic sent from 192.168.0.1, port 5300,
+directed to 192.168.0.5, port 80, and sends it to queue 7::
+
+  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
+  src-port 5300 dst-port 80 action 7
+
+For each flow-type, the programmed filters must all have the same matching
+input set. For example, issuing the following two commands is acceptable::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
+
+Issuing the next two commands, however, is not acceptable, since the first
+specifies src-ip and the second specifies dst-ip::
+
+  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
+  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
+
+The second command will fail with an error. You may program multiple filters
+with the same fields, using different values, but, on one device, you may not
+program two TCP4 filters with different matching fields.
+
+Matching on a sub-portion of a field is not supported by the ixgbe driver, thus
+partial mask fields are not supported.
+
+To create filters that direct traffic to a specific Virtual Function, use the
+"user-def" parameter. Specify the user-def as a 64 bit value, where the lower 32
+bits represents the queue number, while the next 8 bits represent which VF.
+Note that 0 is the PF, so the VF identifier is offset by 1. For example::
+
+  ... user-def 0x800000002 ...
+
+specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
+that VF.
+
+Note that these filters will not break internal routing rules, and will not
+route traffic that otherwise would not have been sent to the specified Virtual
+Function.
+
+Jumbo Frames
+------------
+Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
+to a value larger than the default value of 1500.
+
+Use the ifconfig command to increase the MTU size. For example, enter the
+following where <x> is the interface number::
+
+  ifconfig eth<x> mtu 9000 up
+
+Alternatively, you can use the ip command as follows::
+
+  ip link set mtu 9000 dev eth<x>
+  ip link set up dev eth<x>
+
+This setting is not saved across reboots. The setting change can be made
+permanent by adding 'MTU=9000' to the file::
+
+  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
+  /etc/sysconfig/network/<config_file> // for SLES
+
+NOTE: The maximum MTU setting for Jumbo Frames is 9710. This value coincides
+with the maximum Jumbo Frames size of 9728 bytes.
+
+NOTE: This driver will attempt to use multiple page sized buffers to receive
+each jumbo packet. This should help to avoid buffer starvation issues when
+allocating receive packets.
+
+NOTE: For 82599-based network connections, if you are enabling jumbo frames in
+a virtual function (VF), jumbo frames must first be enabled in the physical
+function (PF). The VF MTU setting cannot be larger than the PF MTU.
+
+Generic Receive Offload, aka GRO
+--------------------------------
+The driver supports the in-kernel software implementation of GRO. GRO has
+shown that by coalescing Rx traffic into larger chunks of data, CPU
+utilization can be significantly reduced when under large Rx load. GRO is an
+evolution of the previously-used LRO interface. GRO is able to coalesce
+other protocols besides TCP. It's also safe to use with configurations that
+are problematic for LRO, namely bridging and iSCSI.
+
+Data Center Bridging (DCB)
+--------------------------
+NOTE:
+The kernel assumes that TC0 is available, and will disable Priority Flow
+Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
+enabled when setting up DCB on your switch.
+
+DCB is a configuration Quality of Service implementation in hardware. It uses
+the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
+different priorities that traffic can be filtered into. It also enables
+priority flow control (802.1Qbb) which can limit or eliminate the number of
+dropped packets during network stress. Bandwidth can be allocated to each of
+these priorities, which is enforced at the hardware level (802.1Qaz).
+
+Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
+802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
+and can accept settings from a DCBX capable peer. Software configuration of
+DCBX parameters via dcbtool/lldptool are not supported.
+
+The ixgbe driver implements the DCB netlink interface layer to allow user-space
+to communicate with the driver and query DCB configuration for the port.
+
+ethtool
+-------
+The driver utilizes the ethtool interface for driver configuration and
+diagnostics, as well as displaying statistical information. The latest ethtool
+version is required for this functionality. Download it at:
+https://www.kernel.org/pub/software/network/ethtool/
+
+FCoE
+----
+The ixgbe driver supports Fiber Channel over Ethernet (FCoE) and Data Center
+Bridging (DCB). This code has no default effect on the regular driver
+operation. Configuring DCB and FCoE is outside the scope of this README. Refer
+to http://www.open-fcoe.org/ for FCoE project information and contact
+ixgbe-eedc@lists.sourceforge.net for DCB information.
+
+MAC and VLAN anti-spoofing feature
+----------------------------------
+When a malicious driver attempts to send a spoofed packet, it is dropped by the
+hardware and not transmitted.
+
+An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
+spoofed packet is detected, the PF driver will send the following message to
+the system log (displayed by the "dmesg" command)::
+
+  ixgbe ethX: ixgbe_spoof_check: n spoofed packets detected
+
+where "x" is the PF interface number; and "n" is number of spoofed packets.
+NOTE: This feature can be disabled for a specific Virtual Function (VF)::
+
+  ip link set <pf dev> vf <vf id> spoofchk {off|on}
+

-
-Command Line Parameters
-=======================
-
-max_vfs
--------
-:Valid Range: 1-63
-
-This parameter adds support for SR-IOV. It causes the driver to spawn up to
-max_vfs worth of virtual functions.
-If the value is greater than 0 it will also force the VMDq parameter to be 1 or
-more.
-
-NOTE: This parameter is only used on kernel 3.7.x and below. On kernel 3.8.x
-and above, use sysfs to enable VFs. Also, for Red Hat distributions, this
-parameter is only used on version 6.6 and older. For version 6.7 and newer, use
-sysfs. For example::
-
-  #echo $num_vf_enabled > /sys/class/net/$dev/device/sriov_numvfs // enable VFs
-  #echo 0 > /sys/class/net/$dev/device/sriov_numvfs               //disable VFs
-
-The parameters for the driver are referenced by position. Thus, if you have a
-dual port adapter, or more than one adapter in your system, and want N virtual
-functions per port, you must specify a number for each port with each parameter
-separated by a comma. For example::
-
-  modprobe ixgbe max_vfs=4
-
-This will spawn 4 VFs on the first port.
-
-::
-
-  modprobe ixgbe max_vfs=2,4
-
-This will spawn 2 VFs on the first port and 4 VFs on the second port.
-
-NOTE: Caution must be used in loading the driver with these parameters.
-Depending on your system configuration, number of slots, etc., it is impossible
-to predict in all cases where the positions would be on the command line.
-
-NOTE: Neither the device nor the driver control how VFs are mapped into config
-space. Bus layout will vary by operating system. On operating systems that
-support it, you can check sysfs to find the mapping.
-
-NOTE: When either SR-IOV mode or VMDq mode is enabled, hardware VLAN filtering
-and VLAN tag stripping/insertion will remain enabled. Please remove the old
-VLAN filter before the new VLAN filter is added. For example,
-
-::
-
-  ip link set eth0 vf 0 vlan 100 // set VLAN 100 for VF 0
-  ip link set eth0 vf 0 vlan 0   // Delete VLAN 100
-  ip link set eth0 vf 0 vlan 200 // set a new VLAN 200 for VF 0
-
-With kernel 3.6, the driver supports the simultaneous usage of max_vfs and DCB
-features, subject to the constraints described below. Prior to kernel 3.6, the
-driver did not support the simultaneous operation of max_vfs greater than 0 and
-the DCB features (multiple traffic classes utilizing Priority Flow Control and
-Extended Transmission Selection).
-
-When DCB is enabled, network traffic is transmitted and received through
-multiple traffic classes (packet buffers in the NIC). The traffic is associated
-with a specific class based on priority, which has a value of 0 through 7 used
-in the VLAN tag. When SR-IOV is not enabled, each traffic class is associated
-with a set of receive/transmit descriptor queue pairs. The number of queue
-pairs for a given traffic class depends on the hardware configuration. When
-SR-IOV is enabled, the descriptor queue pairs are grouped into pools. The
-Physical Function (PF) and each Virtual Function (VF) is allocated a pool of
-receive/transmit descriptor queue pairs. When multiple traffic classes are
-configured (for example, DCB is enabled), each pool contains a queue pair from
-each traffic class. When a single traffic class is configured in the hardware,
-the pools contain multiple queue pairs from the single traffic class.
-
-The number of VFs that can be allocated depends on the number of traffic
-classes that can be enabled. The configurable number of traffic classes for
-each enabled VF is as follows:
-0 - 15 VFs = Up to 8 traffic classes, depending on device support
-16 - 31 VFs = Up to 4 traffic classes
-32 - 63 VFs = 1 traffic class
-
-When VFs are configured, the PF is allocated one pool as well. The PF supports
-the DCB features with the constraint that each traffic class will only use a
-single queue pair. When zero VFs are configured, the PF can support multiple
-queue pairs per traffic class.
-
-allow_unsupported_sfp
----------------------
-:Valid Range: 0,1
-:Default Value: 0 (disabled)
-
-This parameter allows unsupported and untested SFP+ modules on 82599-based
-adapters, as long as the type of module is known to the driver.
-
-debug
------
-:Valid Range: 0-16 (0=none,...,16=all)
-:Default Value: 0
-
-This parameter adjusts the level of debug messages displayed in the system
-logs.
-
-
-Additional Features and Configurations
-======================================
-
-Flow Control
-------------
-Ethernet Flow Control (IEEE 802.3x) can be configured with ethtool to enable
-receiving and transmitting pause frames for ixgbe. When transmit is enabled,
-pause frames are generated when the receive packet buffer crosses a predefined
-threshold. When receive is enabled, the transmit unit will halt for the time
-delay specified when a pause frame is received.
-
-NOTE: You must have a flow control capable link partner.
-
-Flow Control is enabled by default.
-
-Use ethtool to change the flow control settings. To enable or disable Rx or
-Tx Flow Control::
-
-  ethtool -A eth? rx <on|off> tx <on|off>
-
-Note: This command only enables or disables Flow Control if auto-negotiation is
-disabled. If auto-negotiation is enabled, this command changes the parameters
-used for auto-negotiation with the link partner.
-
-To enable or disable auto-negotiation::
-
-  ethtool -s eth? autoneg <on|off>
-
-Note: Flow Control auto-negotiation is part of link auto-negotiation. Depending
-on your device, you may not be able to change the auto-negotiation setting.
-
-NOTE: For 82598 backplane cards entering 1 gigabit mode, flow control default
-behavior is changed to off. Flow control in 1 gigabit mode on these devices can
-lead to transmit hangs.
-
-Intel(R) Ethernet Flow Director
--------------------------------
-The Intel Ethernet Flow Director performs the following tasks:
-
-- Directs receive packets according to their flows to different queues.
-- Enables tight control on routing a flow in the platform.
-- Matches flows and CPU cores for flow affinity.
-- Supports multiple parameters for flexible flow classification and load
-  balancing (in SFP mode only).
-
-NOTE: Intel Ethernet Flow Director masking works in the opposite manner from
-subnet masking. In the following command::
-
-  #ethtool -N eth11 flow-type ip4 src-ip 172.4.1.2 m 255.0.0.0 dst-ip \
-  172.21.1.1 m 255.128.0.0 action 31
-
-The src-ip value that is written to the filter will be 0.4.1.2, not 172.0.0.0
-as might be expected. Similarly, the dst-ip value written to the filter will be
-0.21.1.1, not 172.0.0.0.
-
-To enable or disable the Intel Ethernet Flow Director::
-
-  # ethtool -K ethX ntuple <on|off>
-
-When disabling ntuple filters, all the user programmed filters are flushed from
-the driver cache and hardware. All needed filters must be re-added when ntuple
-is re-enabled.
-
-To add a filter that directs packet to queue 2, use -U or -N switch::
-
-  # ethtool -N ethX flow-type tcp4 src-ip 192.168.10.1 dst-ip \
-  192.168.10.2 src-port 2000 dst-port 2001 action 2 [loc 1]
-
-To see the list of filters currently present::
-
-  # ethtool <-u|-n> ethX
-
-Sideband Perfect Filters
-------------------------
-Sideband Perfect Filters are used to direct traffic that matches specified
-characteristics. They are enabled through ethtool's ntuple interface. To add a
-new filter use the following command::
-
-  ethtool -U <device> flow-type <type> src-ip <ip> dst-ip <ip> src-port <port> \
-  dst-port <port> action <queue>
-
-Where:
-  <device> - the ethernet device to program
-  <type> - can be ip4, tcp4, udp4, or sctp4
-  <ip> - the IP address to match on
-  <port> - the port number to match on
-  <queue> - the queue to direct traffic towards (-1 discards the matched traffic)
-
-Use the following command to delete a filter::
-
-  ethtool -U <device> delete <N>
-
-Where <N> is the filter id displayed when printing all the active filters, and
-may also have been specified using "loc <N>" when adding the filter.
-
-The following example matches TCP traffic sent from 192.168.0.1, port 5300,
-directed to 192.168.0.5, port 80, and sends it to queue 7::
-
-  ethtool -U enp130s0 flow-type tcp4 src-ip 192.168.0.1 dst-ip 192.168.0.5 \
-  src-port 5300 dst-port 80 action 7
-
-For each flow-type, the programmed filters must all have the same matching
-input set. For example, issuing the following two commands is acceptable::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.5 src-port 55 action 10
-
-Issuing the next two commands, however, is not acceptable, since the first
-specifies src-ip and the second specifies dst-ip::
-
-  ethtool -U enp130s0 flow-type ip4 src-ip 192.168.0.1 src-port 5300 action 7
-  ethtool -U enp130s0 flow-type ip4 dst-ip 192.168.0.5 src-port 55 action 10
-
-The second command will fail with an error. You may program multiple filters
-with the same fields, using different values, but, on one device, you may not
-program two TCP4 filters with different matching fields.
-
-Matching on a sub-portion of a field is not supported by the ixgbe driver, thus
-partial mask fields are not supported.
-
-To create filters that direct traffic to a specific Virtual Function, use the
-"user-def" parameter. Specify the user-def as a 64 bit value, where the lower 32
-bits represents the queue number, while the next 8 bits represent which VF.
-Note that 0 is the PF, so the VF identifier is offset by 1. For example::
-
-  ... user-def 0x800000002 ...
-
-specifies to direct traffic to Virtual Function 7 (8 minus 1) into queue 2 of
-that VF.
-
-Note that these filters will not break internal routing rules, and will not
-route traffic that otherwise would not have been sent to the specified Virtual
-Function.
-
-Jumbo Frames
-------------
-Jumbo Frames support is enabled by changing the Maximum Transmission Unit (MTU)
-to a value larger than the default value of 1500.
-
-Use the ifconfig command to increase the MTU size. For example, enter the
-following where <x> is the interface number::
-
-  ifconfig eth<x> mtu 9000 up
-
-Alternatively, you can use the ip command as follows::
-
-  ip link set mtu 9000 dev eth<x>
-  ip link set up dev eth<x>
-
-This setting is not saved across reboots. The setting change can be made
-permanent by adding 'MTU=9000' to the file::
-
-  /etc/sysconfig/network-scripts/ifcfg-eth<x> // for RHEL
-  /etc/sysconfig/network/<config_file> // for SLES
-
-NOTE: The maximum MTU setting for Jumbo Frames is 9710. This value coincides
-with the maximum Jumbo Frames size of 9728 bytes.
-
-NOTE: This driver will attempt to use multiple page sized buffers to receive
-each jumbo packet. This should help to avoid buffer starvation issues when
-allocating receive packets.
-
-NOTE: For 82599-based network connections, if you are enabling jumbo frames in
-a virtual function (VF), jumbo frames must first be enabled in the physical
-function (PF). The VF MTU setting cannot be larger than the PF MTU.
-
-Generic Receive Offload, aka GRO
---------------------------------
-The driver supports the in-kernel software implementation of GRO. GRO has
-shown that by coalescing Rx traffic into larger chunks of data, CPU
-utilization can be significantly reduced when under large Rx load. GRO is an
-evolution of the previously-used LRO interface. GRO is able to coalesce
-other protocols besides TCP. It's also safe to use with configurations that
-are problematic for LRO, namely bridging and iSCSI.
-
-Data Center Bridging (DCB)
---------------------------
-NOTE:
-The kernel assumes that TC0 is available, and will disable Priority Flow
-Control (PFC) on the device if TC0 is not available. To fix this, ensure TC0 is
-enabled when setting up DCB on your switch.
-
-DCB is a configuration Quality of Service implementation in hardware. It uses
-the VLAN priority tag (802.1p) to filter traffic. That means that there are 8
-different priorities that traffic can be filtered into. It also enables
-priority flow control (802.1Qbb) which can limit or eliminate the number of
-dropped packets during network stress. Bandwidth can be allocated to each of
-these priorities, which is enforced at the hardware level (802.1Qaz).
-
-Adapter firmware implements LLDP and DCBX protocol agents as per 802.1AB and
-802.1Qaz respectively. The firmware based DCBX agent runs in willing mode only
-and can accept settings from a DCBX capable peer. Software configuration of
-DCBX parameters via dcbtool/lldptool are not supported.
-
-The ixgbe driver implements the DCB netlink interface layer to allow user-space
-to communicate with the driver and query DCB configuration for the port.
-
-ethtool
--------
-The driver utilizes the ethtool interface for driver configuration and
-diagnostics, as well as displaying statistical information. The latest ethtool
-version is required for this functionality. Download it at:
-https://www.kernel.org/pub/software/network/ethtool/
-
-FCoE
-----
-The ixgbe driver supports Fiber Channel over Ethernet (FCoE) and Data Center
-Bridging (DCB). This code has no default effect on the regular driver
-operation. Configuring DCB and FCoE is outside the scope of this README. Refer
-to http://www.open-fcoe.org/ for FCoE project information and contact
-ixgbe-eedc@lists.sourceforge.net for DCB information.
-
-MAC and VLAN anti-spoofing feature
-----------------------------------
-When a malicious driver attempts to send a spoofed packet, it is dropped by the
-hardware and not transmitted.
-
-An interrupt is sent to the PF driver notifying it of the spoof attempt. When a
-spoofed packet is detected, the PF driver will send the following message to
-the system log (displayed by the "dmesg" command)::
-
-  ixgbe ethX: ixgbe_spoof_check: n spoofed packets detected
-
-where "x" is the PF interface number; and "n" is number of spoofed packets.
-NOTE: This feature can be disabled for a specific Virtual Function (VF)::
-
-  ip link set <pf dev> vf <vf id> spoofchk {off|on}
-

+Linux* Base Virtual Function Driver for Intel(R) 10G Ethernet
+=============================================================
+
+Intel 10 Gigabit Virtual Function Linux driver.
+Copyright(c) 1999-2018 Intel Corporation.
+
+Contents
+========
+
+- Identifying Your Adapter
+- Known Issues
+- Support
+
+This driver supports 82599, X540, X550, and X552-based virtual function devices
+that can only be activated on kernels that support SR-IOV.
+
+For questions related to hardware requirements, refer to the documentation
+supplied with your Intel adapter. All hardware requirements listed apply to use
+with Linux.
+
+
+Identifying Your Adapter
+========================
+The driver is compatible with devices based on the following:
+
+  * Intel(R) Ethernet Controller 82598
+  * Intel(R) Ethernet Controller 82599
+  * Intel(R) Ethernet Controller X520
+  * Intel(R) Ethernet Controller X540
+  * Intel(R) Ethernet Controller x550
+  * Intel(R) Ethernet Controller X552
+  * Intel(R) Ethernet Controller X553
+
+For information on how to identify your adapter, and for the latest Intel
+network drivers, refer to the Intel Support website:
+https://www.intel.com/support
+
+Known Issues/Troubleshooting
+============================
+
+SR-IOV requires the correct platform and OS support.
+
+The guest OS loading this driver must support MSI-X interrupts.
+
+This driver is only supported as a loadable module at this time. Intel is not
+supplying patches against the kernel source to allow for static linking of the
+drivers.
+
+VLANs: There is a limit of a total of 64 shared VLANs to 1 or more VFs.
+
+

+
+https://www.intel.com/support/
+
+or the Intel Wired Networking project hosted by Sourceforge at:
+
+https://sourceforge.net/projects/e1000
+
+If an issue is identified with the released source code on a supported kernel
+with a supported adapter, email the specific information related to the issue
+to e1000-devel@lists.sf.net.
