- Add support for media selection via if_media. If the front-end does not supply media types, default to the "manual" type. - Clean up the ETHER_CMP stuff slightly. - Keep track of our carrier status, for media status requests.

#ifdef DDB

Make the MI LANCE driver standalone, and use cfattach to resolve naming conflicts between bus attachments on ports that can have multiple instances of the LANCE. Changed struct ifnet to have a pointer to the softc of the underlying device and a printable "external name" (name + unit number), thus eliminating if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_start)() to take a struct ifnet *, rather than a unit number.
