====================
wireless-next patches for v5.19

First set of patches for v5.19 and this is a big one. We have two new
drivers, a change in mac80211 STA API affecting most drivers and
ath11k getting support for WCN6750. And as usual lots of fixes and
cleanups all over.

Major changes:

new drivers
 - wfx: silicon labs devices
 - plfxlc: pureLiFi X, XL, XC devices

mac80211
 - host based BSS color collision detection
 - prepare sta handling for IEEE 802.11be Multi-Link Operation (MLO) support

rtw88
 - support TP-Link T2E devices

rtw89
 - support firmware crash simulation
 - preparation for 8852ce hardware support

ath11k
 - Wake-on-WLAN support for QCA6390 and WCN6855
 - device recovery (firmware restart) support for QCA6390 and WCN6855
 - support setting Specific Absorption Rate (SAR) for WCN6855
 - read country code from SMBIOS for WCN6855/QCA6390
 - support for WCN6750

wcn36xx
 - support for transmit rate reporting to user space
