It does not *totally* reverse it -- existing interface names remain
stable in a lot of cases actually, just not with your case where the
firmware decides to rearrange the numbering completely (which should
hopefully not be the majority of cases, given how few reports we get
about it). So IMHO the "(to the level the firmware permits this)"
qualification seems to adequately address that?
