[BusyBox] ethernet interface monitor?

[Marc Karasek]

One way would be thru the interrupt handler.  If the hardware is setup
so that the PHY interrupt is being generated thru the MAC or seperately,
it will trip on any link change (up/down).  You could then do an
interface thru proc to handle the event counts.
