Public bug reported:
As the title says, if there are 2 different ovs ports with the same
external_ids:iface-id field (which is the port_id), when at least one of
them is managed by the ovs agent, it might fail finding the correct one
if they are not connected to the same bridge.
Steps to reproduce:
1. Create a router with an internal port to some Neutron network
2. Find the port in 'ovs-vsctl show'
3. Use the following command to find the port_id in ovs: sudo ovs-vsctl
--columns=external_ids list Interface <port_name>
4. Use the following commands to create a new port with the same field in a new
bridge:
sudo ovs-vsctl add-br a
sudo ip link add dummy12312312 type dummy
sudo ovs-vsctl add-port br-a dummy12312312
sudo ovs-vsctl set Interface dummy12312312 external_ids:iface-id="<port_id>" #
port_id was obtained in point 3.
5. Restart the ovs agent.
At this point the ovs agent's log should show "Port: dummy12312312 is on
br-a, not on br-int".
Expected result: ovs agent should know to iterate though the options and
find the correct port in the correct bridge.
