Hi Ansuel
It is great you are using the LED subsystem for this. But we need to
split the code up into a generic part which can shared by any
switch/PHY and a driver specific part.
There has been a lot of discussion on the list about this. Maybe you
can help get us to a generic solution which can be used by everybody.
