ODROID H2+ plus H2 Net Card - Realtek r8125 drivers

I did have some success using these instructions:

And the experimental kernel from here:

https://people.ipfire.org/~arne_f/highly-experimental/x86_64/

It loaded the kernel (with one ‘FATAL’ error), but it recognised the 6 Realtek NICs. I was able to assign zones to them but… it seems as though the DHCP is not working correctly (I assume?). I was unable to find the IPfire installation and log in to the Web UI.

I am a noob at Linux. Any thoughts welcome!
