It's included where there's a stable address. That's not true for GPIO controlled devices though, it's a GPIO controller plus a number. Ramming lots of information to the media entity's name field is not possible since it's just 32 bytes; for this reason we're looking to implement a better way to recognise devices in MC. But for now, we got to cope with what we have.

Is this one merged already? If yes, sure I can. Otherwise a new version would be nice.
