[midnightengineer]

I am unable to see my ethernet card ports in the OS (Ubuntu 20.04) by doing ip a. I can see the card in lspci and also under lshw. I know (from BIOS menu) that a port in the Card is also connected.
[COLOR=#242729][FONT=Arial]How do I see the network interface actually link up in the OS? Is this a bug with Ubuntu? I have physically verified that the Port on the card is up and blinking.
