Second set of patches for v5.12. Last time there was a smaller pull
request so unsurprisingly this time we have a big one. mt76 has new
hardware support and lots of new features, iwlwifi getting new
features and rtw88 got NAPI support. And the usual cleanups and fixes
all over.
Major changes:
ath10k
* support setting SAR limits via nl80211
rtw88
* support 8821 RFE type2 devices
* NAPI support
iwlwifi
* add new FW API support
* support for new So devices
* support for RF interference mitigation (RFI)
* support for PNVM (Platform Non-Volatile Memory, a firmware data
file) from BIOS
mt76
* add new mt7921e driver
* 802.11 encap offload support
* support for multiple pcie gen1 host interfaces on 7915
* 7915 testmode support
* 7915 txbf support
brcmfmac
* support for CQM RSSI notifications
wil6210
* support for extended DMG MCS 12.1 rate

MT7921 contains a microprocessor with which the host can use command/event
to communicate to implement offload features such as establish connection,
hardware scan and so on. The host has to download the ROM patch, RAM
firmware and finally activate the MCU to complete the MT7921
initialization.
