Johannes Berg says:

====================
We have a number of changes, but things are settling down:
 * a fix in the new 6 GHz channel support
 * a fix for recent minstrel (rate control) updates
   for an infinite loop
 * handle interface type changes better wrt. management frame
   registrations (for management frames sent to userspace)
 * add in-BSS RX time to survey information
 * handle HW rfkill properly if !CONFIG_RFKILL
 * send deauth on IBSS station expiry, to avoid state mismatches
 * handle deferred crypto tailroom updates in mac80211 better
   when device restart happens
 * fix a spectre-v1 - really a continuation of a previous patch
 * advertise NL80211_CMD_UPDATE_FT_IES as supported if so
 * add some missing parsing in VHT extended NSS support
 * support HE in mac80211_hwsim
 * let mac80211 drivers determine the max MTU themselves
along with the usual cleanups etc.
====================
