41 state change will trigger the events, for consumption by an
42 LED class driver. There are triggers for each link speed currently
43 supported by the PHY and also a one common "link" trigger as a

45 All these triggers are named according to the following pattern:
46 <mii bus id>:<phy>:<speed>

48 Where speed is in the form:
49 <Speed in megabits>Mbps OR <Speed in gigabits>Gbps OR link
