Merge tag 'mac80211-next-for-davem-2016-07-06' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
One more set of new features:
* beacon report (for radio measurement) support in cfg80211/mac80211
* hwsim: allow wmediumd in namespaces
* mac80211: extend 160MHz workaround to CSA IEs
* mesh: properly encrypt group-addressed privacy action frames
* mesh: allow setting peer AID
* first steps for MU-MIMO monitor mode
* along with various other cleanups and improvements
====================
