Merge tag 'wireless-next-2022-07-13' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next
Johannes Berg says:
====================
A fairly large set of updates for next, highlights:
ath10k
* ethernet frame format support
rtw89
* TDLS support
cfg80211/mac80211
* airtime fairness fixes
* EHT support continued, especially in AP mode
* initial (and still major) rework for multi-link
operation (MLO) from 802.11be/wifi 7
As usual, also many small updates/cleanups/fixes/etc.
====================
