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
====================
