Hi Lars

I did not see these patches earlier, but i've been looking at the
switch driver patches recently, so went digging.

Can the Ethernet switch itself control these LEDs for indicating
things like packet receive/transmit, link state, and link speed? Or
are they purely software controlled?

    Thanks
	Andrew
