The 10.14.3 updated killed my ethernet. I have a Intel 82574L pcie card, and used Intel82574.kext that always worked without issues. The kext is in Library/Extensions, but before this update it also worked if I put it in EFI/Clover/Kexts/Other or in IONetworkfamily.kext as a plugin. I had it in all 3 locations (one at the time) and it always worked, the reason I had it in Library/Extension lately is because I read in a guide that’s where it’s best to keep it.
Anyhow, since the first Mojave...
