Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless

John W. Linville says:

====================
Here is another batch of fixes intended for the 3.12 stream...

For the mac80211 bits, Johannes says:

"This time I have two fixes for IBSS (including one for wext, hah), a fix
for extended rates IEs, an active monitor checking fix and a sysfs
registration race fix."

On top of those...

Amitkumar Karwar brings an mwifiex fix for an interrupt loss issue
w/ SDIO devices.  The problem was due to a command timeout issue
introduced by an earlier patch.

Felix Fietkau a stall in the ath9k driver.  This patch fixes the
regression introduced in the commit "ath9k: use software queues for
un-aggregated data packets".

Stanislaw Gruszka reverts an rt2x00 patch that was found to cause
connection problems with some devices.
