Merge tag 'mac80211-for-davem-2018-09-03' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
Here are quite a large number of fixes, notably:
* various A-MSDU building fixes (currently only affects mt76)
* syzkaller & spectre fixes in hwsim
* TXQ vs. teardown fix that was causing crashes
* embed WMM info in reg rule, bad code here had been causing crashes
* one compilation issue with fix from Arnd (rfkill-gpio includes)
* fixes for a race and bad data during/after channel switch
* nl80211: a validation fix, attribute type & unit fixes
along with other small fixes.
