Merge branch 'wireless'

John W. Linville says:

====================
Here is a batch of fixes intended for the 3.10 stream.

Amitkumar Karwar provides an mwifiex fix to plug a memory leak when
the driver is unloaded.

Bing Zhao brings an mwifiex fix for some flag handling that leads to
log spam and an unusable interface.

Daniel Drake offers an mwifiex fix for multicast filter setup, to
correctly implement wakeup behaviour for multicast WOL.

Felix Fietkau fixes an ath9k problem that produces logspam and keycache
errors due to a bad return code.

Stanislaw Gruszka produces an fix for a WARNING from ath5k, and an
iwl4965 workaround to stop advertising a feature that doesn't work with
the current mac80211 implementation.

Sujith Manoharan gives us an ath9k fix to reprogram the HW beacon timers
after a TSF update, and an initvals fix for the AR9565 device.

Thommy Jakobsson fixes an rx descriptor underrun on b43.
