Merge tag 'mac80211-next-for-davem-2018-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says: ==================== Highlights: * merge net-next, so I can finish the hwsim workqueue removal * fix TXQ NULL pointer issue that was reported multiple times * minstrel cleanups from Felix * simplify lib80211 code by not using skcipher, note that this will conflict with the crypto tree (and this new code here should be used) * use new netlink policy validation in nl80211 * fix up SAE (part of WPA3) in client-mode * FTM responder support in the stack ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
