I have some good news for all CE users that has a box with JL2101 phy: I’ve ported the JL2101 PHY driver to CE’s kernel, and it works perfectly fine!

Backstory: Even I was lucky to get a non-JL2101 HK1 RBOX X4, I was still hit by it as I bought another S905X3 HK1 BOX for tinkering and without any surprise it came with the notorious JL2101.

The driver is not directly available on JLsemi’s website but I managed to find it in the format of patches in embedfire’s LubanCatWrt (an OpenWrt fork) repo for their DoorNet2 for the Rockchip 5.4 kernel they are using. The driver was ported to some other OpenWrt forks as well. After porting the driver and backporting some macros from newer kernels and the driver successfully builds and loads and works with high load for several hours.

I’ll clean up the code a little bit and opened a PR tomorrow to merge this driver into CE’s kernel : )
