Merge tag 'mac80211-next-for-davem-2018-10-12' of... 

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
====================
