Merge tag 'mac80211-next-for-davem-2015-04-10' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
There isn't much left, but we have
* new mac80211 internal software queue to allow drivers to have
shorter hardware queues and pull on-demand
* use rhashtable for mac80211 station table
* minstrel rate control debug improvements and some refactoring
* fix noisy message about TX power reduction
* fix continuous message printing and activity if CRDA doesn't respond
* fix VHT-related capabilities with "iw connect" or "iwconfig ..."
* fix Kconfig for cfg80211 wireless extensions compatibility
====================
