RealTek RTL8126 5Gbps Ethernet PCIe Support

adam23 · July 11, 2024 at 7:36 AM

Hi,

I bought a RealTek RTL8126 NIC that I use in my AsRock J4205-ITX System running the recent LE 12.0.0 version.

Unfortunalty the current image is missing the driver to support the card.

Is there a way to ask for support in LE for this piece of hardware ?

Thanks

Please run "dmesg | paste" and "lscpi -nv | paste" and share the URLs so we can see if anything is in the boot log (missing firwmare or such) and what the card IDs are. It should be supported in Linux 6.9.y https://github.com/torvalds/linux…44c4b9203f3ec9a unless it's not the same card variant or has different PCI device IDs.

dmesg: https://paste.libreelec.tv/fresh-calf.log

lspci -nv: https://paste.libreelec.tv/devoted-grub.log

Do you think I can just build kernel 6.9.x or does LibreElec apply some special patches ?

I've created a fresh image based on LE 12.0.0 and Kernel v6.9.8.

The card is detected and functional.

Getting around ~220mb/s up/down which is not bad for 25 SGD$ and running on a Intel J4205
