(Realtek rtl8125) 2.5GBe ethernet not working on AMD B550 mobo

Hi ,

After each kernel update , you must re install ethernet driver .

So for removing :

sudo modprobe -rfv r8125
sudo dkms remove -m r8125 -v 9.003.05 --all
sudo rm -r /usr/src/r8125-9.003.05

then reinstall with the initial procedure seen before .
