This bug is critical for proper sr-iov agent functioning in regards to QoS. You may even consider it a security threat because you don't apply the expected bandwidth limit to ports. I raised the Importance, and target it for M1.

    Add network_update RPC into SR-IOV agent

    SR-IOV agent doesn't listen for network_update notification, but it's
    desired in QOS when network updated with a new QOS policy. This patch
    adds it into this agent.
