Merge tag 'mac80211-next-for-davem-2020-07-31' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
We have a number of changes
 * code cleanups and fixups as usual
 * AQL & internal TXQ improvements from Felix
 * some mesh 802.1X support bits
 * some injection improvements from Mathy of KRACK
   fame, so we'll see what this results in ;-)
 * some more initial S1G supports bits, this time
   (some of?) the userspace APIs
====================
