====================
wireless-next patches for v6.1

Few stack changes and lots of driver changes in this round. brcmfmac
has more activity as usual and it gets new hardware support. ath11k
improves WCN6750 support and also other smaller features. And of
course changes all over.

Note: in early September wireless tree was merged to wireless-next to
avoid some conflicts with mac80211 patches, this shouldn't cause any
problems but wanted to mention anyway.

Major changes:

mac80211

 - refactoring and preparation for Wi-Fi 7 Multi-Link Operation (MLO)
  feature continues

brcmfmac

 - support CYW43439 SDIO chipset

 - support BCM4378 on Apple platforms

 - support CYW89459 PCIe chipset

rtw89

 - more work to get rtw8852c supported

 - P2P support

 - support for enabling and disabling MSDU aggregation via nl80211

mt76

 - tx status reporting improvements

ath11k

 - cold boot calibration support on WCN6750

 - Target Wake Time (TWT) debugfs support for STA interface

 - support to connect to a non-transmit MBSSID AP profile

 - enable remain-on-channel support on WCN6750

 - implement SRAM dump debugfs interface

 - enable threaded NAPI on all hardware

 - WoW support for WCN6750

 - support to provide transmit power from firmware via nl80211

 - support to get power save duration for each client

 - spectral scan support for 160 MHz

wcn36xx

 - add SNR from a received frame as a source of system entropy
