I was hoping someone else would suggest that. :) I pondered having an IFM_ETHER2,
but that would be fugly. It is also convenient that the media word is stable
across major versions. However, it seems to me if we want to reinvent this we
should actually convert this to a struct instead of packing everything into a
single word, and have the struct have various fields, and possibly split "speed"
from "cable type".
