RE: XGMII New electrical Characteristics
Yong,
Regarding "technical_required_change NO votes:" it MUST be recognized that
each "NO vote" must be accompanied by a proposed remedy. Said remedy, to be
adopted as part of a subsequent draft, MUST receive at least 75% approval.
I am taking some risk here, so please accept this comment in the spirit in
which it is given:
To cast a no vote exclusively because one does not agree with the decision
of the body at large is not likely to be a productive activity. While we
would never turn down a comment, or even discourage input, we do need to
focus on those things that will correct, refine, and otherwise improve the
draft standard. Every individual needs to apply their own filter before
taking the "pen in hand." I would suggest that "disagreement," alone may not
be a sufficient metric.
