* EFIStudio / Ethernet / Add Device: I get "Device path not found! Ethernet not available on this machine!"
* Removing devices in System/Network Preferences and removing /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist
* Setting EthernetBuiltIn to Yes
* Setting PCIRootID to 1 or to 0
* Setting my device as a MacBook Air, via Champlist, since those do not have ethernet either.
* Installing PDANet to try to act as a fake ethernet adapter (but I can't move it from en1 to en0)
* And a wide variety of other solutions
