* net: stmmac: dwmac-rk: Add handling for RGMII_ID/RXID/TXIDWadim Egorov2017-03-301-16/+37
| | | | | | | | | | | | | | ATM dwmac-rk will always set and enable it's internal delay lines. Using PHY internal delays in combination with the phy-mode rgmii-id/rxid/txid was not possible. Only rgmii was supported. Now we can disable rockchip's gmac delay lines and also use rgmii-id/rxid/txid. Tested only with a RK3288 based board.

Preethi changes the default driver mode of operation to descriptor write-back for VF. Alex cleans up and addresses several issues in the way that i40e handles private flags. Modifies the driver to use the length of the packet instead of the DD status bit to determine if a new descriptor is ready to be processed. Refactors the driver by pulling the code responsible for fetching the receive buffer and synchronizing DMA into a single function. Also pulled the code responsible for handling buffer recycling and page counting and distributed it through several functions, so we can commonize the bits that handle either freeing or recycling the buffers. Cleans up the code in preparation for us adding support for build_skb(). Changed the way we handle the maximum frame size for the receive path so it is more consistent with other drivers. Paul enables XL722 to use the direct read/write method since it does not support the AQ command to read/write the control register. Christopher fixes a case where we miss an arq element if a new one is added before we enable interrupts and exit the loop. Jake cleans up a pointless goto statement. Also cleaned up a flag that was not being used. Carolyn does round 2 for adding a delay to the receive queue to accommodate the hardware needs. ==================== Signed-off-by: David S.

| * i40e/i40evf: Change the way we limit the maximum frame size for RxAlexander Duyck2017-03-296-27/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the way we handle the maximum frame size for the Rx path. Previously we were rounding up to 2K for a 1500 MTU and then brining the max frame size down to MTU plus a fixed amount. With this patch applied what we now do is limit the maximum frame to 1.5K minus the value for NET_IP_ALIGN for standard MTU, and for any MTU greater than 1500 we allow up to the maximum frame size. This makes the behavior more consistent with the other drivers such as igb which had similar logic. In addition it reduces the test matrix for MTU since we only have two max frame sizes that are handled for Rx now.

It is then the responsibility of the function that pulls the data to either increment the pagecnt_bias if the buffer can be recycled as-is, or to update page_offset so that we are pointing at the correct location for placement of the next buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The goto found here for when in MFP mode is pointless. It jumps to the end of a series of if blocks. However, right after this statement is a closing '}' for this if block, which will result in the program flow going to the exact same location as the goto statement indicates. Thus, regardless of whether we are in MFP mode, the program flow will resume from the same location. This arose due to various refactoring which did not notice that this goto became essentially a no-op. To properly understand this diff you will need to view a larger context than is given by default.

| * i40e: Clean up handling of private flagsAlexander Duyck2017-03-292-85/+112
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch cleans up and addresses several issues in the way that i40e handles private flags. Previously the code was choosing fixed bits and trying to match them up with strings in a somewhat haphazard way. This resulted in the possibility for adding a new bit and causing a mismatch as the private flags are linear bits starting at 0, and the private flags in the driver were split up over a group specific to the PF and a group that was global. What this change does is define an array of structs used to represent the private flags. Contained within the structs are the bits necessary to know which flags to set and/or clear depending on the state of the bit. By doing this we can add new bits in the future with minimal overhead and avoid creating possible mis-matches should we need to remove a flag based on compile options.

The offloaded SW mechanism is TC's pedit action. The offloading is supported for E-Switch steering of VF traffic in the SRIOV switchdev mode and for NIC (non eswitch) RX. One use-case for this offload on virtual networks, is when the hypervisor implements flow based router such as Open-Stack's DVR, where L2 headers of guest packets re-written with routers' MAC addresses and the IP TTL is decremented. Another use case (which can be applied in parallel with routing) is stateless NAT where guest L3/L4 headers are re-written. The series is built as follows: the 1st six patches are preperations which don't yet add new functionality, patches 7-8 add the FW APIs (data-structures and commands) for header re-write, and patch nine allows offloading driver to access pedit keys. The 10th patch is somehow the core of the series, where we translate from the pedit way to represent set of header modification elements to the FW API for that same matter. Once a set of HW modification is established, we register it with the FW and get a modify header ID. When this ID is used with an action during packet steering, the HW applies the header modification on the packet. Patches 11 and 12 implement the above logic as an offload for pedit action for the NIC and E-Switch use-cases. I'd like to thanks Elijah Shakkour <elijahs@mellanox.com> for implementing and helping me testing this functionality on HW simulator, before it could be done with FW. ==================== Signed-off-by: David S.

User-space provides set of keys where each one of them is made of: command (add or set), header-type, byte offset within that header along with a 32 bit mask and value. The mask dictates what bits in the 32 bit word that starts on the offset we should be dealing with, but under negative polarity (unset bits are to be modified). We do a 1st pass over the set of keys while using the header-type and offset to fill the masks and the values into a data-structure containting all the supported network headers. We then do a 2nd pass over the set of fields to re-write supported by the HW, where for each such candidate field, we use the masks filled on the 1st pass to realize if we should offloading re-write it. In case offloading is required, we fill a HW descriptor with the following: (1) the header field to modify (2) the bit offset within the field from where to modify (set command only) (3) the value to set/add (4) the length in bits 1...32 to modify (set command only) Note that it's possible for a given pedit mask to dictate modifying the same header field multiple times or to modify multiple header fields. Currently such combinations are not supported for offloading, hence, for set commands, the offset within the field is always zero, and the length to modify is the field size.

Currently we are not leaking things (e.g eswitch vlan reference, encap reference and HW resources) since the main code to add flower rules does a cleanup by calling mlx5e_tc_del_flow(). This cleanup further works just b/c we're checking there if the HW rule for the flow we are attempting to delete is valid before touching it, and since under the current possible combinations of supported actions it's okay to go and blidnly deref or delete all the action related resources (encap, vlan). Instead, do things properly, namely make sure that if add flow fails we clean all what was allocated or referenced. Now, the flow delete code can blindly deref/deallocate both the rule and the actions related resources and when more action combinations are introduced (such as the upcoming header re-write) we are fine with clear and robust code. While here, align all of nic/fdb parse actions/add flow functions to get mlx5e_tc_flow struct param and pick the attributes or whatever else needed from there.

In order to make that possible, let's do the following: - descend into drivers/net/phy/ unconditionally - make mdiobus_setup_mdiodev_from_board_info() take a callback argument which allows us not to expose the internal MDIO board info list and mutex, yet maintain the logic within the same file - relocate the code that creates a MDIO device into drivers/net/phy/mdio_bus.c - build mdio-boardinfo.o into the kernel as soon as MDIO_DEVICE is defined (y or m) Fixes: 90eff9096c01 ("net: phy: Allow splitting MDIO bus/device support from PHYs") Fixes: 648ea0134069 ("net: phy: Allow pre-declaration of MDIO devices") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Tested-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: David S.

The first patch is needed to break an include loop between netdevice.h, dsa.h and devlink.h. We need to remove dsa.h from netdevice.h. As a result, some files fail to compile, because they require includes pulled in via dsa.h. So this patch adds a number of includes in various places. The majority is within the network subsystem, but cifs also needs a few fixes. 0-day has been chewing on this for over a day now, and not found any breakage. But Arnd's randconfig might uncover something. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is an include loop between netdevice.h, dsa.h, devlink.h because of NETDEV_ALIGN, making it impossible to use devlink structures in dsa.h. Break this loop by taking dsa.h out of netdevice.h, add a forward declaration of dsa_switch_tree and netdev_set_default_ethtool_ops() function, which is what netdevice.h requires. No longer having dsa.h in netdevice.h means the includes in dsa.h no longer get included. This breaks a few other files which depend on these includes. Add these directly in the affected file.
