Setup

Attention⚠️, only support official firmware. If you are compiling your own firmware, please refer to the scripts in the action.

First, download the corresponding ipk file according to your version, scp it to your device, and then run

opkg -i kmod-r8125_4.14.275+9.011.01-x86-0_x86_64.ipk

If you are using the 5.15 kernel, the r8196 driver should automatically drive your network card. If you want to force the use of the driver from this project, you can delete the r8196 driver.

QA

if you're not the right speed, please check this command.

openwrt snapshot linux 6.1.29 driver autoneg stick to 1000mb/s, forcing via ethtool works

I was able to compile on openwrt snapshot using kernal 6.1.29 (for the nanopi R5C),

yet I see 1 PCI error (copy paste below) after boot/init and the interface if stuck in 1000 ful-duplex until I force it with ethtool (then it works ok full speed)

Any idea where this could come from or if you experience the 1Gps issue?

r8125b跑不满带宽？

我直接clone你的r8125源码，加入到openwrt官方master分支编译，软路由J4125+r8125b安装pve+openwrt，总是跑不满带宽，1000M的宽带，只能跑600多～700多的样子，是什么情况？你有这种情况吗？

RSS question

Hi! Thank you for releasing drivers with RSS for openwrt!
i can't get the documentation, you set 2 cores for intel i211 2 queues for 2 nic's

For example i have x2 i210 nic's with 4 queues and 2 core 4 thread cpu, should i put RSS=4,8? or 2,4? RSS=x,y?

支持内核5.15.38吗？

内核5.15.38 好像安装不了

Is there any chance for the intel i226-v driver port to the kernel 4.14.275 (OpenWrt 19.07.x) ?

First, thanks for the GREAT job 👍 , the r8125b 2.5G NIC works very well on my X86 Router (OpenWrt 19.07.10).
Now I'm going to buy another machine :
( https://cwwk.net/products/the-12th-generation-u-series-small-and-large-core-mixed-architecture-mini-host )
It is built in with 6 intel i226-v NIC.
For some reason, I'd like to run OpenWrt 19.07.10, because the kernel 4.14.275 is more stable than the kernel 5.x .
Could you please compile a driver ipk for the OpenWrt 19.07.x with intel i226-v NIC ?
Thank you very much.
