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
