Well, if we're going to add rawip support, why bother emulating a
netdev at all?  I guess because it's convenient and we don't have to
destroy the existing wwan0 and create some other tun-type device
instead.  But still, seems odd that we'd set raw-ip mode and then
emulate ethernet when all that's really going back and forth is IP.
