Some questions before upgrading from HS to Catalina

Hardware — ASRock Z77 Extreme6, Ivy Bridge i5 3470.

1. Ethernet — BCM57781, currently works through FakePCIID. Does that kext still works in Catalina, or I'll need to install another ethernet card?
2. WiFi — Atheros 9287, currently works through spoofing ID (some ProbookAtheros.kext). As I read, I'll have to replace whole IO80211Family.kext. Can I inject it, or the only way is to replace it in /S/L/E? I'll very much prefer vanilla mode.
3. SATA — I have to deal with famous bug in HS AppleAHCIPort, via a couple Clover patches. Do I still need them in Catalina, and if yes, do I need to update them?
