Merge tag 'mac80211-for-davem-2018-07-24' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
Only a few fixes:
* always keep regulatory user hint
* add missing break statement in station flags parsing
* fix non-linear SKBs in port-control-over-nl80211
* reconfigure VLAN stations during HW restart
====================
