ar5523

* add support for SMCWUSBT-G2 USB device

iwlwifi

* support new versions of the FTM FW APIs

* support new version of the beacon template FW API

* print some extra information when the driver is loaded

rtw88

* support wowlan feature for 8822c

* add support for WIPHY_WOWLAN_NET_DETECT

brcmfmac

* add initial support for monitor mode

qtnfmac

* add module parameter to enable DFS offloading in firmware

* add support for STA HE rates

* add support for TWT responder and spatial reuse
