Merge tag 'mac80211-next-for-davem-2019-09-11' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
