Re: Unified PMD vs. Unified PHY


By UniPHY, are you referring to Frazier's specific proposal, or a more general
unified phy?

The proposal presented by H. Frazier glossed over many details of the
interworking --
and we all know that without the details, almost anything that has Unification
as a keyword sounds good. And of course, given *no* additional constraints about
compatibility with existing infrastructure, and bandwidth efficiency, a "uniphy"
sounds great. But it is only with these additional constraints that the question
makes sense.
