I don't care much either way, lan-0 is okay as is lan-led.
but...
+ label = "nanopi-r4s:green:lan";
+ label = "nanopi-r4s:red:sys";
+ label = "nanopi-r4s:green:wan";
It would be good to have common labels, that means LED_FUNCTION_LAN,
LED_FUNCTION_WAN, and figuring out something better than "sys",
possibly LED_FUNCTION_FAULT?
Thanks,
Pavel
