After the initial probe, set up all port leds:
- Disable all LEDs
- Enable netdev trigger for all green LEDs (tp + sfp)
- Enable link statux and rx/tx activity
- Skip all aux LEDs
Also in script, a neat little flash function that can be used both for a
production test, to verify all LEDs work, and at runtime to locate the
device in a rack of devicess.
