Fort the musycc and if_mn drivers I ended up giving the nodes names
from the physical location on the pci bus, so they are called
things like:
sync-0-10-0
sync-0-9-0
etc.
I wouldn't mind if we could standardize the interface in general btw,
it would make it a lot easier for FreeBSD users if they can just plug
in a supported card and see things work the same, nomatter which card.
I'm not saying that the way I designed the interface for the musycc or
if_mn are ideal, but at least they work in production...
