It does now...question is whether it should?  Xorp has no concept
of delete interface v/s remove xorp configuration for interface.

I was thinking that if xorp didn't create the VLAN itself, it
should not delete the VLAN from the OS when removing xorp
configuration for that interface.

That's easily enough done, but might not be flexible enough
for all users...

Perhaps a better way would be an explicit per-interface flag that
users could set..but that is a lot code...
