See the previous discussion about the raw backend from Or's original
patch. There's no obvious reason why we should have this in addition to
a tun/tap backend.
The only use-case I know of is macvlan but macvtap addresses this
functionality while not introduce the rather nasty security problems
associated with a raw backend.
