87b6cf51ac cxgb4: set skb->rxhash
Implement the ->set_flags ethtool method to control NETIF_F_RXHASH and

212f9934af bnx2: Prevent "scheduling while atomic" warning with cnic, bonding and vlan.
The bonding driver calls ndo_vlan_rx_register() while holding bond->lock.
The bnx2 driver calls bnx2_netif_stop() to stop the rx handling while
changing the vlgrp.  The call also stops the cnic driver which sleeps
while the bond->lock is held and cause the warning.

This code path only needs to stop the NAPI rx handling while we are
changing the vlgrp.  Since no reset is going to occur, there is no need
to stop cnic in this case.  By adding a parameter to bnx2_netif_stop()
to skip stopping cnic, we can avoid the warning.

c441b8d2cb bnx2: Fix lost MSI-X problem on 5709 NICs.
It has been reported that under certain heavy traffic conditions in MSI-X
mode, the driver can lose an MSI-X vector causing all packets in the
associated rx/tx ring pair to be dropped.  The problem is caused by
the chip dropping the write to unmask the MSI-X vector by the kernel
(when migrating the IRQ for example).

This can be prevented by increasing the GRC timeout value for these
register read and write operations.

Thanks to Dell for helping us debug this problem.

c0dfb90e5b ixgbe: ixgbe_down needs to stop dev_watchdog
There is a small race between when the tx queues are stopped
and when netif_carrier_off() is called in ixgbe_down.  If the
dev_watchdog() timer fires during this time it is possible for
a false tx timeout to occur.

This patch moves the netif_carrier_off() so that it is called before
the tx queues are stopped preventing the dev_watchdog timer from
detecting false tx timeouts.  The race is seen occosionally when
FCoE or DCB settings are being configured or changed.

Testing note, running ifconfig up/down will not reproduce this
issue because dev_open/dev_close call dev_deactivate() and then
dev_activate().

f8d1dcaf88 ixgbe: enable extremely low latency
82598/82599 can support EITR == 0, which allows for the
absolutely lowest latency setting in the hardware.  This disables
writeback batching and anything else that relies upon a delayed
interrupt. This patch enables the feature of "override" when a
user sets rx-usecs to zero, the driver will respect that setting
over using RSC, and automatically disable RSC.  If rx-usecs is
used to set the EITR value to 0, then the driver should disable
LRO (aka RSC) internally until EITR is set to non-zero again.

6f461f6c7c e1000e: enable/disable ASPM L0s and L1 and ERT according to hardware errata
Prompted by a previous patch submitted by Matthew Garret <mjg@redhat.com>,
further digging into errata documentation reveals the current enabling or
disabling of ASPM L0s and L1 states for certain parts supported by this
driver are incorrect.  82571 and 82572 should always disable L1.  For
standard frames, 82573/82574/82583 can enable L1 but L0s must be disabled,
and for jumbo frames 82573/82574 must disable L1.  This allows for some
parts to enable L1 in certain configurations leading to better power
savings.

Also according to the same errata, Early Receive (ERT) should be disabled
on 82573 when using jumbo frames.

The old device trees are buggy, though having a dead ethernet is
better than a dead kernel, so fix the issue by using of_iomap().

Also, a somewhat similar issue exist in the probe() routine, though
there the oops is only a possibility. Nonetheless, fix it too.

03ceedea97 ath9k: Group Key fix for VAPs
When I set up multiple VAPs with ath9k, I encountered an issue that
the traffic may be lost after a while.

The detailed phenomenon is
1. After a while the clients connected to one of these VAPs will get
into a state that no broadcast/multicast packets can be transfered
successfully while the unicast packets can be transfered normally.
2. Minutes latter the unitcast packets transfer will fail as well,
because the ARP entry is expired and it can't be freshed due to the
broadcast trouble.

It's caused by the group key overwritten and someone discussed this
issue in ath9k-devel maillist before, but haven't work out a fix yet.

I referred the method in madwifi, and made a patch for ath9k.
The method is to set the high bit of the sender(AP)'s address, and
associated that mac and the group key. It requires the hardware
supports multicast frame key search. It seems true for AR9160.

Not sure whether it's the correct way to fix this issue. But it seems
to work in my test. The patch is attached, feel free to revise it.

72fd071833 bnx2x: Parity errors handling for 57710 and 57711
This patch introduces the parity errors handling code for 57710 and 57711 chips.

HW is configured to stop all DMA transactions to the host and sending packets to the network
once parity error is detected, which is meant to prevent silent data corruption.
At the same time HW generates the attention interrupt to every function of the device where parity
has been detected so that driver can start the recovery flow.

The recovery is actually resetting the chip and restarting the driver on all active functions
of the chip where the parity error has been reported.
