Hi, this appears to have broken DVR functionality for a simple shared
tenant network. The DVR flows translating the DVR macs are missing on
the physical bridges now for a VLAN based network. This tenant network
is shared, and only attached to 1 router.
As you can see port_shared_only is set to True here because its shared
and not an external network.

I think we need more checks here - seems like it was intended only for a shared
network that acts as a link between 2 routers, but doesnt attach any compute
ports?
