Public bug reported:

On a running instance, we have had several occasions of network issues.

During the last issue we noticed that the interfaces lost their vlan tags in openvswitch:
ovs-vsctl show |grep qg-fb5a3595-48 -A 10
        Port "qg-fb5a3595-48"
            Interface "qg-fb5a3595-48"
                type: internal
---

A complete restart of neutron-l3-agent caused a migration and now it works with a different vlan tag:
ovs-vsctl show |grep -A 10 qg-fb5a3595-48                                                                                                                                                                      
        Port "qg-fb5a3595-48"
            tag: 52
            Interface "qg-fb5a3595-48"
                type: internal
---

How is this possible?
