Hi Matthias

I was more thinking of adding a new driver call to the PHY driver API,
to configure an LED. Something like

rtl8211e_config_leds(phydev, int led, struct phy_led_config cfg);

It would be called by the phylib core after config_init(). But also,
thinking ahead to generic linux LED support, it could be called later
to reconfigure the LEDs to use a different trigger. The standard LED
sysfs interface would be used.
