Frode Nordahl 675b109d54 Optionally limit number of units to get port attached
This is useful for validating deployments with OVN where it is not
required to have external networking attached to every chassis.

Any chassis that does not have external networking directly
attached will forward traffic destined for the external network
through a tunnel to a chassis that does.
