BCM4322 100% ok Big Sur & Catalina Opencore/Clover

BCM4322 was officially dropped in Catalina (AirPortBrcm4331 kext was no more) but installing Mojave's (or High Sierra's) IO80211Family kext in /L/E or in /S/L/E (to replace the vanilla version) perfectly worked as a workaround.

Looks like the kext you posted is Mojave 10.14.6's latest IO802Family kext v12.0 with just AirPortBrcm4331 kext v8.0 in the PlugIns folder, itself having its Info.plist scope reduced to pci14e4,432b.

 

Thanks for confirming the old trick still works in Big Sur.
