Kalle Valo says:

====================
wireless-drivers-next patches for v5.10

Second set of patches for v5.10. Biggest change here is wcn3680
support to wcn36xx driver, otherwise smaller features. And naturally
the usual fixes and cleanups.

Major changes:

brcmfmac

* support 4-way handshake offloading for WPA/WPA2-PSK in AP mode

* support SAE authentication offload in AP mode

mt76

* mt7663 runtime power management improvements

* mt7915 A-MSDU offload

wcn36xx

* add support wcn3680 Wi-Fi 5 devices

ath11k

* spectral scan support for ipq6018
====================
