I ran out of PCIe slots on my hack so I put my AX210 inside a Thunderbolt PCIe enclosure. At first the driver would not work because it's missing IOPCITunnelCompatible key in its Info.plist. After adding it manually in everything seems to work fine except hotplugging (tried both AirportItlwm and itlwm). So could you please allow this key to be added into the plist? I should be able to open a PR for this relatively simple change.
