register a netdevice that can never become active.

Thats similar to a ethernet device that never has a cable
plugged in. You should register the device with its carrier
turned off, then change the carrier state once the connection
has been established.
I would also encourage you to embrace this view of the VNIC as a
tunnel fully and let the administrator re-target an active netdevice
to a different VNIC without tearing down the netdevice..
Maybe I misparsed this, sorry Jason :)
