Recently I put together a driver for an Ether-board that uses the Intel
82586 controller. As part of the software initialization I had it do
a TDR check. It was useful for testing the cable, and more importantly,
the drop cable and connectors.

However, there were circumstances where the TDR check failed -- mainly
on broadband networks and over-extended Ethernets.

If you do the TDR it would probably be useful to add an option to bypass
the test for those nets on which it fails but not as a result of an error.
