iwlagn: workaround bug crashing some APs

2011-09-16T19:32:12+00:00

This patch reverts commit 9b7688328422b88a7a15dc0dc123ad9ab1a6e22d which
was introduced in 2.6.38-rc1.  It works around a problem where the iwlagn
driver stimulates a bug crashing (requiring power cycle to recover) some
APs under heavy traffic.

rtl2800usb: Fix incorrect storage of MAC address on big-endian platforms

2011-09-16T19:32:10+00:00

The eeprom data is stored in little-endian order in the rt2x00 library.
As it was converted to cpu order in the read routines, the data need to
be converted to LE on a big-endian platform.

Using gcc 4.4.5 on a Powerbook G4 with a PPC cpu, a complicated
if statement results in incorrect flow, whereas the equivalent switch
statement works correctly.

    mac80211: fix suspend/resume races with unregister hw

Above commit add rtnl_lock() into wiphy_register(), what cause deadlock
when initializing ipw2x00 driver, which itself call wiphy_register()
from register_netdev() internal callback with rtnl mutex taken.

To fix move wiphy_register() outside register_netdev(). This solution
have side effect of not creating /sys/class/net/wlanX/phy80211 link,
but that's a minor issue we can live with.

iwlagn: fix command queue timeout

2011-09-13T18:32:02+00:00

If the command queue is constantly busy,
which can happen in P2P, the hangcheck
timer will frequently find a command in
it and will eventually reset the device
because nothing sets the timestamp for
this queue when commands are processed.

Fix this by setting the timestamp when
a command completes.

iwlagn: fix stack corruption

2011-09-13T18:18:39+00:00

Alexander reported a strange crash in iwlagn that
Meenakshi and Wey couldn't reproduce. I just ran
into the same issue and tracked it down to stack
corruption. This fixes it.

ath9k: Fix kernel panic on unplugging the device

2011-09-13T18:18:39+00:00

when the device is yanked out ath_pci_remove starts doing the cleanups,
unregistering the hardware etc. so we should bail out immediately when
we get drv_flush callback from mac80211 when the card is being unplugged.
the panic occurs after we had associated to an AP.
