Raspberry Pi Kernel recompile for waveshare 1Gbit Network interface was created by mediocre_chloride

Hi all
My goal is to setup a raspberry pi with ethercat.

I have a raspberry Pi 5 with an additional network interface from waveshare ( here )
its planned to use this additional ethernet port for connecting the machine to the network, and the native Port on the Pi for Ethercat.
to use this additional Interface, the kernel needs to be recompiled with some additions to the config file.

I am not familiar with recompiling a kernel, thats why i am seeking help here.

Has anyone encountered similar issues?
Is there maybe a fixed Kernel to download so i dont need to do the recompile?

greetings
Marc

Shouldn't need recompiling as, our images use a kernel built from the Raspberry Pi GitHub sources.
The only difference being is choosing the kernel config option for real time.
If the standard kernel doesn't work give me a yell and I'll build an update image, as there are a few minor things I would like to add.

Thanks for the fast reply

I Downloaded 2.94 Rpi 5 based OS from the official linuxcnc/download site.

The Waveshare user guide states that something in the lines of:
Device Drivers
> Network device support
    > Ethernet driver support
       > Realtek devices
          > Realtek 8169/8168/8101/8125 ethernet support

needs to be added if not using original rpi os.
i am pretty sure that is the problem, as i see the card with lspci as described in the user guide:

but not in ifconfig:

it is also stated, drivers could be installed manually but its not recommended.
Also, there are other rpi linuxcnc distros floating around, do you think its worth switching around?

Like I said the kernel in the image is the same as the RPi OS (with realtime added)

Driver is there:

You may have to check dmesg for any references to R8169. PCIe should be enabled, I used a NVMe boot drive. Remember that the location of config.txt is

/boot/broadcom/config.txt

I sure this is mentioned in the main image RPi5 thread.

Seems the card uses a R8168 interface. The R8168 requires a DKMS driver to get acceptable RT performance. Not sure how that goes with a Pi. I would not use it for ethercat but would be fine for general network use.
