This cannot be enabled because you don't have CONFIG_RTL8169 enabled.

There are a bunch of other symbols that are in this defconfig that don't 
need to be or are not applicable. Can you please send a v3 after running 
make savedefconfig and copying defconfig to 
configs/9tripod-x3568-v4-rk3568_defconfig?

If you edited the defconfig by hand, please avoid as it's error-prone, 
simply use make menuconfig and enable the options you want through the 
menu (and save before exiting). Then run make savedefconfig as 
instructed above to get the defconfig to put into the source code.

Cheers,
Quentin
