Title:
  DVR: stale fip namespaces are not cleaned up on compute nodes

Status in neutron:
  Fix Released

Bug description:
  Scenario:
   - have VM with floating ip
   - l3 agent on compute node goes down
   - VM is deleted
   - server removes router from l3 agent on compute node
   - l3 agent goes up
   - l3 agent cleans stale qrouter namespace, fip namespace remains
  As a result there might be troubles when further associating floating ips with VMs on that compute node due to stale interfaces in fip namespace.
