Merge tag 'mac80211-for-davem-2019-01-25' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211



Johannes Berg says:

====================
Just a few small fixes:
 * avoid trying to operate TDLS when not connection,
   this is not valid and led to issues
 * count TTL-dropped frames in mesh better
 * deal with new WiGig channels in regulatory code
 * remove a WARN_ON() that can trigger due to benign
   races during device/driver registration
 * fix nested netlink policy maxattrs (syzkaller)
 * fix hwsim n_limits (syzkaller)
 * propagate __aligned(2) to a surrounding struct
 * return proper error in virt_wifi error path
====================
