Add support for Atheros Wi-Fi

[unitedastronomer]

High Sierra was the last OS that provided native support for Atheros Wi-Fi functionality. Starting Mojave, it requires injecting some kexts from HS — this works from Mojave through Big Sur, however requires OCLP's root patching starting Monterey.

Required kexts: MinKernel : 18.0.0

• corecaptureElCap.kext
• IO80211ElCap.kext
  • AirportAtheros40.kext

. + some OCLP required settings & kexts.

Available on OCLP's repo, Payloads folder.

Supported by AirportAtheros40.kext:

"168c-30", // AR93xx
"168c-2a", // AR928X
"106b-86", // Unreleased device
"168c-1c", // AR242x / AR542x
"168c-23", // AR5416
"168c-24",  // AR5418

Supported AR928X but reports different device-id, requires spoof:

"168c-002b", // and/or 2b?
"168c-002e", // and/or 2e?

Supported by spoofing:

"168c-34", // AR9462 & AR9463
"168c-36", // AR9565
"168c-37" // AR9485

These however requires an ATH9Kinjector, ATH9KFixup + boot-arg only on <= High Sierra to fix support loading the S/L/E's kexts. They're not needed on => Mojave.

Device Properties for those who needs spoofing:

device-id = 2A000000
compatible = pci168c,2a
IOName = pci168c,2a (helps OCLP detect "Legacy Wireless")

Note that on older Acer laptops, Wi-Fi is not enumerated in ACPI at all, meaning OpenCore won't apply those device properties unless given a name (such as ARPT).
