Hardware support in Ubuntu Core for a Realtek RTL8125 2.5GbE Controller

I am looking for information relating to hardware support in Ubuntu Core, for a Realtek RTL8125 2.5GbE Controller (rev 05) on a RAK7391.

We have recently purchased a RAK7391 WisGate Connect, it includes a 1Gbe POE port which works as expected, along with the a 2.5Gbe RTL8125 port which is not working with Ubuntu Core, it works under Raspbian.

I had a look in the /snap/pi-kernel/current/lib/modules/5.15.0-1070-raspi/kernel/drivers/ directories to see if it was listed there and I can’t see it.

Can anyone tell me if it’s possible to get the drivers for this ethernet port incorporated into the Canonical pi-kernel snap so it would be natively supported?

Here is a link to the ethernet portion of the datasheet for this device https://docs.rakwireless.com/product-categories/wisgate/rak7391/datasheet#ethernet-1

Have you checked with Ubuntu Core 24 yet? It comes with a 6.8 kernel…

(The driver for this card should be r8169 which is usually shipped in the kernel nowadays …)

Thank you, I didn’t think to test Core24, when I can I will test and update the thread with the outcome.

I have tried installing the Core24 snap on my image, which doesn’t seem to have worked, am I right in thinking I would need to rebase my image to Core24 for the newer Kernel?

Yes, seems I was not clear above, you should indeed use a complete UbuntuCore24 system …
