RE: Hari and train-up sequences


I agree that if it is done correctly, then signaling link faults via
auto-negotiation is quite elegant.  The problem lies in the fact that link
fault (or remote fault) signaling was optional and it was sometimes
misinterpreted by the implementor.  Remote fault indication in the
auto-negotiation base page was a source of numerous problems during the UNH
IOL connectivity tests, as was it an issue during Microsoft certification
testing.  The concept behind it was great, but in practicality, it created
more headaches than it was worth and most people abandoned it.

	One of the advantages to providing an "auto-negotiation" type
	path is in signalling link faults.
