652bf64622 be2net: Fix wrong status getting returned for MCC commands
MCC Response CQEs are processed as part of NAPI poll routine and
also synchronously. If MCC completions are consumed by NAPI poll
routine, wrong status is returned to synchronously waiting routine.
Fix this by getting status of MCC command from command response
instead of response CQEs.

af311fe310 be2net: Fix traffic stall INTx mode
EQ is getting armed wrongly in INTx mode as INTx interrupt is taking
some time to deassert. This can cause another interrupt while NAPI is
scheduled and scheduling a NAPI in interrupt does not take effect.
This causes interrupt to be missed and traffic stalls. Fixing this by
preventing wrong arming of EQ.

VLAN and multicast hardware filters are limited and can get
exhausted in adapters with many PCI functions. If setting

ad12886091 ath9k: Fix IDLE Powersave
* PS_WAIT_FOR_TX_ACK is used in network-sleep mode and checking
  it for handling IDLE transitions is incorrect. Fix this.

* RX PCU/DMA engines have to be stopped before setting the chip into
  full-sleep mode - otherwise the chip becomes mute.

* Make things a bit clear by checking explicitly for network-sleep
  mode in the tx() routine and add a couple of debug statements
  to aid PS debugging.

a334872224 bnx2x: add afex support
Following patch adds afex multifunction support to the driver (afex
multifunction is based on vntag header) and updates FW version used to 7.2.51.

Support includes the following:

1. Configure vif parameters in firmware (default vlan, vif id, default
   priority, allowed priorities) according to values received from NIC.
2. Configure FW to strip/add default vlan according to afex vlan mode.
3. Notify link up to OS only after vif is fully initialized.
4. Support vif list set/get requests and configure FW accordingly.
5. Supply afex statistics upon request from NIC.
6. Special handling to L2 interface in case of FCoE vif.

0586a11b5c rt2800: add chipset revision RT5390R support
About 70% of the chips with revision RT5390R initialize incorrectly, using
the auxiliary antenna instead of the main one. The net result is that
signal reception is very poor (no AP further than 1M).

This chipset differs from RT5390 and RT5390F by its support of hardware
antenna diversity. Therefore antenna selection should be done
differently, by disabling software features and previously selected
antenna.

This changeset does just that, and makes all RT5390R work properly.

This is based on Ralink's 2012_03_22_RT5572_Linux_STA_v2.6.0.0_DPO

7c5adc8d83 ath9k_hw: fix and clean up PHY activation delay
The delay calculation is the same for all chips, however some parts of the
code missed the extra delay factor for half/quarter.
Clean up the code and move the delay calculation to a common place.

For some reason the MAC timing is a bit off when waiting for ACKs, so add

AR9462 uses modified version of 3-Wire hw scheme for btcoex.
MCI itself is not a separate hw scheme but it aids to manage

75acd5a82a ath9k: fix TX power reporting on AR9003 chips
The current code unconditionally reads the target
power values for all modes from the EEPROM. However
In 'ar9003_hw_set_power_per_rate_table' the regulatory
caps are applied only on a mode specific subset of the
power values.

The reported TX power level is calculated from the
maximum of the power values. Because some of these
values are uncapped in certain cases, the reported
TX power will be wrong.

On the older chipset, we don't have such problems
because only the mode specific subset of the power
levels are retrieved from the EEPROM on those. Do
the same for the AR9003 chips to fix the issue.

792df87228 net/hyperv: Adding cancellation to ensure rndis filter is closed
Although the network interface is down, the RX packets number which
could be observed by ifconfig may keep on increasing.

This is because the WORK scheduled in netvsc_set_multicast_list()
may be executed after netvsc_close(). That means the rndis filter
may be re-enabled by do_set_multicast() even if it was closed by
netvsc_close().

By canceling possible WORK before close the rndis filter, the issue
could be never happened.

c5a99937a9 ks8851: Fix mutex deadlock in ks8851_net_stop()
There is a potential deadlock scenario when the ks8851 driver
is removed. The interrupt handler schedules a workqueue which
acquires a mutex that ks8851_net_stop() also acquires before
flushing the workqueue. Previously lockdep wouldn't be able
to find this problem but now that it has the support we can
trigger this lockdep warning by rmmoding the driver after
an ifconfig up.

Fix the possible deadlock by disabling the interrupts in
the chip and then release the lock across the workqueue
flushing. The mutex is only there to proect the registers
anyway so this should be ok.
