Well, as the post states I have a Ethernet port showing unknown after a reboot. Been running for a few years fine. Tried rebooting and restarting the network manager but I’m a loss here. Hardware is a nuc11 with an i7 and 2.5 gbe nic

Update: I have found the NIC, it’s showing as “unclaimed”.
You haven’t given any info on your environment, but does it show up in the OS? In lspci or nmtui or whatever? Is it listed in /etc/network/interfaces or your distro’s equivalent?
It does not show up in the network manager (Fedora). Ifconfig also only shows loopback and wifi.
I did now find it at the bottom of the command so that’s something at least.

Try booting from a live disk. If it works there, it’s probably an update or config change that’s causing problems.
Booting into an old kernel fixed it
