Realtek r8125 ethernet drivers no longer build on Linux

Hi,

This looks to be a regression upstream in the Linux ethernet APIs but I can no longer build and install the proprietary realtek r8125 ethernet drivers on arch from here (https://www.realtek.com/Download/List?cate_id=584). I reached out to realtek on nicfae@realtek.com but not sure how responsive they'd be. I tried taking a look at the new keee abstraction but I'm not sure what changes I have to make to translate from old to new on my own :-(. Asking here in case anyone else has any idea.

After downloading r8125-9.013.02 and running

sudo ./autorun.sh

I get:

Check old driver and unload it.
Build the module and install

For context, I didn't know my motherboard (https://www.msi.com/Motherboard/MAG-X57 … K-MAX-WIFI) needed proprietary drivers when I got it. The ones shipping with Linux don't seem to be able to detect the ethernet device (wifi works fine) when I plug it in. If alternatively someone can suggest how to get the native ethernet drivers working I'd appreciate it.

Edit:

Sorry, forgot to list Linux kernel version XD.

Re: Realtek r8125 ethernet drivers no longer build on Linux

https://aur.archlinux.org/packages/r8125-dkms

Using the AUR is almost always a better idea than just straight from the manufacturer. Patches are often required, as the kernel very often changes things that break out of tree modules. It hasn't been fixed in the AUR package, but it's being discussed there and there's a patch.

Looks like someone contributed a patch here https://aur.archlinux.org/packages/r8125-dkms

Ah, thanks. Gonna try just installing this (I had been meaning to setup a dkms wrapper but this is even better).
