Perhaps a dumb question here, but why would you do that?  The whole
point of an etherstub object is that it's not connected to the outside
world.  And if you want a connection to the outside world, why not just
create the vnic on top of a real link?

That aside, I think you might get further using 'dladm create-simnet'
rather than an etherstub.  A simnet is a simulated Ethernet interface.

As for the "STATE unknown" bit, I believe that's because etherstubs
don't have physical links and thus don't have physical link status.
It's probably harmless.
