RE: Hari and train-up sequences

If it didn't work, then it may not have been specified correctly.  I
presume that most people were able to get 8b10b coding to work.  I would
imagine that they also got other components of the autonegotiation process
(like link speed, duplex, etc) to work.  If I'm correct, then it seems that
the mechanism isn't flawed, but rather its use :-)
