I'd recommend using one of the actual QoS qdiscs (htb or hfsc) instead
of ingress policing.  Ingress policing causes no end of trouble and
often simply doesn't work.  (This isn't an OVS bug--OVS just
configures the ingress policing settings built into the Linux kernel.)

But: Is there anything in the log about failing to configure ingress
