Is anyone here using the "Realtek 8126VB 5Gbps"?

[lekto]

Hi, I'm looking for a motherboard for my new PC; the cheapest that looks good to me is "MSI PRO X870-P WIFI", it has a Realtek 8126 Ethernet chip. I looked up this chip, and I see mixed results:
- People are complaining about it not working.
- People mention driver on the Realtek website, but I don't know which, or if it is in the Gentoo repo.
- Most probes on linux-hardware.org (https://linux-hardware.org/?view=search&name=RT8126#list) are failed.

Anyone here is using this chip and can share their own opinion on it?

Hello,

I faced the same issue and I was able to make it work installing the drivers from here:
https://github.com/openwrt/rtl8126

Don't know exactly how that fit into a gentoo installation but it should work normally.

I also work a blog post here that show to install it if you are not familiar how to install it from the sources:

Realtek does provide the driver on their website: https://www.realtek.com/Download/List?cate_id=584 but only mentions kernel up to 6.9

Kernel 6.12.x certainly references an 8126A chip as part of the r8169 ethernet driver in code (but not in the menuconfig help).

I cannot comment on how well it works, but this is where you will find it going forward as this driver is continually updated with new RealTek ethernet chips.
