Title:
  Attribute Error found with router_interface_delete

Status in OpenStack Neutron (virtual network service):
  Fix Released

Bug description:
  This may be related to the DB lockwait timeout issue seen in the neutron with DVR.
  The error occurs when trying to query the ports in the "delete_csnat_router_interface".

  This is from the recent change in the router and port relationship.
