Can we maybe change the dummy device weight as emacs get added to a
MAL ?

Dave, the main point of my initial email was: should we provide a
routine from the net core to initialize such dummy devices properly ?
I'm a little worried that some day, the NAPI code will change and the
initialisations done by the driver will not be enough anymore...

Cheers,
Ben.
