No network with Realtek RTL8125 2.5GbE R8169/R8125

Motherboard: Gigabyte B550i Aorus MX Pro

Kernel: Linux archlinux 5.10.0-1-mainline

Drivers tried: r8169, r8125

Attempted: DHPC (gets IP on boot but no network, no IP on subsequent config/service reloads), static IP (same result).

At one stage, [inline]ethtool -s eno1 speed 100[/inline] resulted in working network, setting back to 1000 and back to 100 no longer worked.

Been trying for a few hours so I may have missed some info from attempts/

$ ethtool eno1

Re: No network with Realtek RTL8125 2.5GbE R8169/R8125

It looks like the active driver is the r8169 driver. Have you tried blacklisting it?

This is what I have for kernel 5.9.14-zen1-1-zen:
cat /etc/modprobe.d/r8169.conf

blacklist r8169

EDIT: I have r8125-dkms package from AUR installed as well.

Have tried with r8125-dkms and also r8125 from https://github.com/LouisTakePILLz/r8125/ with neither giving results, with r8169 blacklisted

The module did not load?  The device was not detected by the module?  There device did not detect a link,  could not obtain an IP e.t.c.?  Please provide specifics.
