4: but eth1 didn’t show in ifconfig. what should I do to enable eth1

Thank you very much!
Best regards!!

I don’t know why it didn’t show up, but I’d start by looking at the most verbose output of lspci. What do you get from this?
sudo lspci -vvv -s 01:00.0

Right now it looks like it is loading a driver, so it probably should exist, but there might be errors. You might also provide a full boot log via serial console since what goes on during boot likely has a clue. See:
