Merge tag 'mac80211-next-for-davem-2017-10-11' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
Work continues in various areas:
 * port authorized event for 4-way-HS offload (Avi)
 * enable MFP optional for such devices (Emmanuel)
 * Kees's timer setup patch for mac80211 mesh
   (the part that isn't trivially scripted)
 * improve VLAN vs. TXQ handling (myself)
 * load regulatory database as firmware file (myself)
 * with various other small improvements and cleanups

I merged net-next once in the meantime to allow Kees's
timer setup patch to go in.
====================
