I did a bit of the fleshing out; it can be found at:


on branch dps8m.

The 'ready' bits on the interface needs some work. The "cable" is
implemented as UDP packets; probably the code should periodically send
packets if the interface is enabled and the other end should keep a timeout
counter to detect the other end not ready.
