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