What sorts of hooks can I include in my designs to allow
run-time testing of 100BaseTX hardware?

Obviously, I can monitor traffic, throughput, CRC errors,
etc. to give me a feel for degradation of the overall link.

But, what can I do to diagnose things like cabling problems
and failures without impacting the quality of the link
hardware "otherwise"?  (think "built in cable tester")

An even tougher question:  can I leverage a *partially*
functional cable/interface to provide *limited* connectivity
in the event of a failure that impacts the normal NIC-pair?
(even if this is an either-or implementation)
