Merge tag 'mac80211-for-davem-2017-01-13' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211



Johannes Berg says:

====================
We have a number of fixes, in part because I was late
in actually sending them out - will try to do better in
the future:
 * handle VHT opmode properly when hostapd is controlling
   full station state
 * two fixes for minimum channel width in mac80211
 * don't leave SMPS set to junk in HT capabilities
 * fix headroom when forwarding mesh packets, recently
   broken by another fix that failed to take into account
   frame encryption
 * fix the TID in null-data packets indicating EOSP (end
   of service period) in U-APSD
 * prevent attempting to use (and then failing which
   results in crashes) TXQs on stations that aren't added
   to the driver yet
====================
