Public bug reported:

Refer to this patch(Apply QoS policy on network:router_gateway :https://review.openstack.org/#/c/425218/),I apply qos policy to router gateway port.
Execution command：
ovs-vsctl list interface qg-xxxx
I find that the ingress rate limit of qg port has been configured successfully,but I found this rate limit didn't work by using iperf test.By view the openvswitch log,i find error:

----------------------------------------------------------------------------------
 I think openvswitch don't support police rate of namespace qg port, so neutron don't support Router gateway rate limit.
