This might become more useful now that we have support for PHY & MAC
LEDs. You can use the netdev trigger for the usual things an RJ45 LED
shows: link, rx/tx activity, link speed etc. But they are just Linux
LEDs, you can also use them for heartbeat, disc IO, tty IO, or xt_LED.
xt_LED would actually make sense for an LED in a RJ45 socket.
