Title:
  Nicira plugin: remove_router_interface fail with HTTP 404

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

Bug description:
  {path-to-neutron}/plugins/nicira/NeutronPlugin.py:
  remove_router_interface always fail with HTTP 404.

  I found remove_router_interface sends following http request twice.
  The 1st response is OK (successfully removed) so the other one throws 404 error.
  /ws.v1/lrouter/{router_id}/lport/{switch_id}

  There are 2 methods related to this operation.
  1819: super(NvpPluginV2, self).remove_router_interface(context, router_id, interface_info)
  1851: nvplib.delete_router_lport(self.cluster, router_id, lrouter_port_id)

  [ Workaround ]
  When I comment out 1851, the method doesn't throw 404 error any more.
