Nomenclature is very important, no excuse necessary.
You are right that SGMII is not the term I am looking for, but I am not
sure 1000base-X is either. I am looking for a word that describes the
serial interface that can run in either 1000base-X or 100base-FX mode
(and possibly other ancient/proprietary modes). Maybe just "serdes"?
