You know, I would give my left shift key to figure out to implement media
sense detection on the original Uthernet (in other words, when the cable
comes out or in).

Now there's this silly status byte you can poll that is LinkOK but that
times out after 50 MS! What do to? Well you can test for TxOK, which I do.
And then if you get 2 or three failures in a row then the cable is probably
unplugged. At this point you could test the LinkOK bit.

Great. It's not a work of beauty, but it's not too bad either.

Now how to detect the cable being plugged back in??!! Just blindly send
Ethernet frames until one succeeds? What!

Regarding TCP: ain't gonna happen until I've got a clock card giving me at
least 1 second IRQs. No way, man. Not gonna go down the software loop timer
path!
