Problem: 1 of the NICs on my Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Card is disappearing and not showing up in the OS or the Interface. The other ETH4 is there.

Diagnostic is attached. I have already deleted network.cfg and associated files and rebooted many times with various configs. It did show up originally. I configured it, then it disappeared and won't come back.
