Ante, what do you think?

I didn't remember we ever having encountered this issue but we must have
as I've seen 2 management LAN ports in our published BOMs, right?

We'd certainly be interested in a patch to auto-detect, but how
successful could it be in guessing, and when it guesses wrong, what
would the mitigation be?
