Q: Mac Pro does not recognize Ethernet ports
After a reboot for my late 2013 Mac Pro running OS X 10.11.3, both Ethernet ports are no longer recognized. Both say "Not Connected" although one of them is.
I have:
- rebooted a couple of times
- reset PRAM
- left the power disconnected for several minutes
- tried two different end devices
- tried two different Ethernet cables
- tried both Ethernet ports
The indicator light on the end device flashes.
WiFi works fine.
What else should I do before deciding there's a hardware problem?

Mac Pro, OS X El Capitan (10.11.3)

There was a recent post of the same problem and a solution was found. Give it a try: Re- Built-in ethernet vanished.
