Remove injectors for AirPortBrcm4360 and AirPortBrcmNIC from main Info.plist and move them into separate plugins AirPortBrcm4360_Injector and AirPortBrcmNIC_Injector (kexts with plist only). Under 11.0 (Big Sur) plugin AirPortBrcm4360_Injector.kext must be blocked by MaxKernel 19.9.9 or just removed, otherwise it will block loading of AirPortBrcmNIC since class AirPortBrcm4360 is unsupported.
