Kalle Valo says:

====================
wireless-drivers-next patches for v5.8

Third set of patches for v5.8. Final new features before the merge
window (most likely) opens, noteworthy here is adding WPA3 support to
old drivers rt2800, b43 and b43_legacy.

Major changes:

ath10k

* SDIO and SNOC busses are not experimental anymore

ath9k

* allow receive of broadcast Action frames

ath9k_htc

* allow receive of broadcast Action frames

rt2800

* enable WPA3 support out of box

b43

* enable WPA3 support

b43_legacy

* enable WPA3 support

mwifiex

* advertise max number of clients to user space

mt76

* mt7663: add remain-on-channel support

* mt7915: add spatial reuse support

* add support for mt7611n hardware

iwlwifi

* add ACPI DSM support

* support enabling 5.2GHz bands in Indonesia via ACPI

* bump FW API version to 56
