The SH7757's ETHER and GETHER use common MDIO pin. The MDIO pin is
selected by specific register. So this patch adds new interface in
bb_info, and when the sh_eth driver use the mdio, the register can
be changed by the function.

The previous code had hardcoded the PHY_INTERFACE_MODE_MII of phy_connect.
So some Gigabit PHYs will not behave correctly.
The patch adds the phy_interface in sh_eth_plat_data, so we can select
the phy interface.

The SH7763 has GETHER. So the specification of some registers differs than
other CPUs. This patch removes almost #ifdef of CONFIG_CPU_SUBTYPE_SH7763.
Then we are able to add other CPU's GETHER easily.

I intend to turn struct flowi into a union of AF specific flowi

The PFC configuration is not cleared until the device is reset. This
has not been a problem because setting DCB attributes forced a
hardware reset. Now that we no longer require this reset to occur
PFC remains configured even after being disabled until the
device is reset.
This removes a goto in the PFC hardware set routines for 82598 and
82599 devices that was short circuiting the clear.

Implemented ixgbe_ndo_set_vf_bw function which is being used by iproute2
tool. In addition, updated ixgbe_ndo_get_vf_config function to show the
actual rate limit to the user.
The rate limitation can be configured only when the link is up and the
link speed is 10Gb.
The rate limit value can be 0 or ranged between 11 and actual link
speed measured in Mbps. A value of '0' disables the rate limit for
this specific VF.
iproute2 usage will be 'ip link set ethX vf Y rate Z'.
After the command is made, the rate will be changed instantly.
To view the current rate limit, use 'ip link show ethX'.
The rates will be zeroed only upon driver reload or a link speed change.
This feature is being supported by 82599 and X540 devices.

DCB provides a guaranteed bandwidth in the case with 0%
bandwidth then no bandwidth is guaranteed. However the
traffic class should still be able to transmit traffic.
For this to work the traffic class must be given the

The VF mailbox polling for acks and messages would reset the timer to zero
on a timeout. Under heavy load a timeout may actually occur without being
the result of an error and when this occurs it is not practical to perform
a full VF driver reset on every message timeout. Instead, just return an
error (which is already done) and the VF driver will have an opportunity
to retry the operation.

DCB settings are cleared in the hardware across link events
during ifup ixgbe reprograms the hardware for DCB if it is

use the correct set of configuration data.
This patch checks the dcbx_cap bits and then enables the
device in the correct mode.

This patch adds support to use the priority assignment
table in the ieee_ets structure to map priorities to
traffic classes. Previously ixgbe only supported a
1:1 mapping. Now we can enable and disable hardware
DCB support when multiple traffic classes are actually
being used. This allows the default case all priorities
mapped to traffic class 0 to work in normal hardware
mode and utilize the full packet buffer.
This patch does not address putting the hardware in
4TC mode so packet buffer space may be underutilized
in this case. A follow up patch can address this
optimization. But at least we have the hooks to do
this now.
Also CEE will behave as it always has and map priorities
1:1 with traffic classes.

This enables multiple {Tx|Rx} rings per traffic class while in DCB
mode. In order to get this working as expected the tc_to_tx net
device mapping is configured as well as the prio_tc_map.
skb priorities are mapped across a range of queue pairs to get
a distribution per traffic class. The maximum number of
queue pairs used while in DCB mode is capped at 64. The hardware
max is actually 128 queues but 64 is sufficient for now and
allocating more seemed a bit excessive. It is easy enough to
increase the cap later if need be.
To get the 802.1Q priority tags inserted correctly ixgbe was
previously using the skb queue_mapping field to directly set
the 802.1Q priority. This no longer works because we have removed
the 1:1 mapping between queues and traffic class. Each ring
is aligned with an 802.1Qaz traffic class so here we add an
extra field to the ring struct to identify the 802.1Q traffic
class. This uses an extra byte of the ixgbe_ring struct
fortunately there was a 2byte hole,
struct ixgbe_ring {
void * desc; /* 0 8 */
struct device * dev; /* 8 8 */
struct net_device * netdev; /* 16 8 */
union {
struct ixgbe_tx_buffer * tx_buffer_info; /* 8 */
struct ixgbe_rx_buffer * rx_buffer_info; /* 8 */
}; /* 24 8 */
long unsigned int state; /* 32 8 */
u8 atr_sample_rate; /* 40 1 */
u8 atr_count; /* 41 1 */
u16 count; /* 42 2 */
u16 rx_buf_len; /* 44 2 */
u16 next_to_use; /* 46 2 */
u16 next_to_clean; /* 48 2 */
u8 queue_index; /* 50 1 */
u8 reg_idx; /* 51 1 */
u16 work_limit; /* 52 2 */
/* XXX 2 bytes hole, try to pack */
u8 * tail; /* 56 8 */
/* --- cacheline 1 boundary (64 bytes) --- */
Now we can set the VLAN priority directly and it will be
correct. User space can indicate the 802.1Qaz priority
using the SO_PRIORITY setsocket() option and QOS layer will
steer the skb to the correct rings. Additionally using
the multiq qdisc with a queue_mapping action works as
well.

This implements dcbnl get and set capabilities ops. The
devices supported by ixgbe can be configured to run in
IEEE or CEE modes but not both.
With the DCBX set capabilities bit we add an explicit
signal that must be used to toggle between these modes.
This patch adds logic to fail the CEE command set_hw_all()
which programs the device with a CEE configuration if
the CEE caps bit is not set. Similarly, IEEE set
commands will fail if the IEEE caps bit is not set. We
allow most CEE config set commands to occur because they
do not touch the hardware until set_hw_all() is called.
The one exception to the above is the {set|get}app routines.
These must always be protected by caps bits to ensure
side effects do not corrupt the current configured mode.
By requiring the caps bit to be set correctly we can
maintain a consistent configuration in the hardware
for CEE or IEEE modes and prevent partial hardware
configurations that may occur if user space does
not send a complete IEEE or CEE configurations.
It is expected that user space will signal a DCBX mode
before programming device.

This updates the p54spi Kconfig help text.
The driver works well on n8x0, so remove the words "experimental" and "untested".

My commit 466a19a003f3b45a755bc85f967c21da947f9a00 "iwlwifi: move rx
handlers code to iwl-rx.c" breaks compilation on 32 bits. Fix that.

It seems ath5k has issues receiving broadcast packets (ARPs) when
using multiple STA interfaces associated with multiple APs.
This patch ensures the NIC is always in PROMISC mode if there
are more than 1 stations associated.

Usually H/W generate statistics notify once per about 100ms, but
sometimes we can receive notify in shorter time, even 2 ms.
This can be problem for plcp health and ack health checking.
I.e. with 2 plcp errors happens randomly in 2 ms duration, we
exceed plcp delta threshold equal to 100 (2*100/2).
Also checking ack's in short time, can results not necessary false
positive and firmware reset, for example when channel is noised and
we do not receive ACKs frames or when remote device does not send
ACKs at the moment.
Patch change code to do statistic check and possible recovery only
if 99ms elapsed from last check. Forced delay should assure we have
good statistic data to estimate hardware state.

Put generic rx_handlers (except iwlagn_rx_reply_compressed_ba) to
iwl-rx.c . Make functions static and change prefix from iwlagn_ to
iwl_ . Beautify iwl_setup_rx_handlers and do some other minor coding
style changes.

Now that all accesses to the data_queue structures is done via the specialized
rt2x00queue_get_tx_queue function or via direct accesses, there is no
need for the rt2x00queue_get_queue function anymore, so remove it.

In the spirit of optimizing the code to get the queue structure of TX queues,
also optimize the code to get beacon queues. We can simply use the bcn queue
field of the rt2x00_dev structure instead of using the rt2x00queue_get_queue
function.

The ATIM queue is considered to be a TX queue by the drivers that support
the queue. Therefore include support for the ATIM queue to the
rt2x00queue_get_tx_queue function so that the drivers that support the ATIM
queue can also use that function.
Add the support in such a way that drivers that do not support the ATIM
queue are not penalized in their efficiency.

Current code for the atim queue is strange, as it is considered in the
rt2x00_dev structure as a second beacon queue.
Normalize this by letting the atim queue have its own struct data_queue
pointer in the rt2x00_dev structure.
