Merge tag 'mac80211-next-for-net-next-2020-02-24' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next
Johannes Berg says:
====================
A new set of changes:
* lots of small documentation fixes, from Jérôme Pouiller
* beacon protection (BIGTK) support from Jouni Malinen
* some initial code for TID configuration, from Tamizh chelvam
* I reverted some new API before it's actually used, because
it's wrong to mix controlled port and preauth
* a few other cleanups/fixes
====================
