Major changes:

ath10k

* limit available channels via DT ieee80211-freq-limit

wil6210

* add 802.11r Fast Roaming support for AP and station modes

* add support for channel 4

iwlwifi

* new FW API handling

* some improvements in the PCI recovery mechanism

* enable a new scanning feature;

* continued work on HE (mostly radiotap)

* TKIP implementation in new devices

* work continues for new 22560 hardware

mt76

* add support for Alfa AWUS036ACM

* lots of refactoring to make it easier to add new hardware support

* prepare for adding mt76x0e (pci-e variant) support

* add CONFIG_MT76x0E kconfig symbol

brcmfmac

* add support CYW89342 mini-PCIe device

* add 4-way handshake offload detection for FT-802.1X

* enable NL80211_EXT_FEATURE_CQM_RSSI_LIST
