I'm afraid I don't see your problem at all. My em interfaces appear as they should, even if not connected to a switch. And when I connect an em interface to a switch, I get link and things work as expected. > Steps to reproduce: > 1) Switch your PC/laptop off.

This may well be the case - but not that the em driver handles several different chip models. You may have a problem which is specific to one or a few chip models.
