Comment 6 for bug 1736674

This is now called with the patch identified: https://github.com/openstack/neutron/blob/master/neutron/plugins/ml2/drivers/linuxbridge/agent/extension_drivers/qos_driver.py#L106-L110

Maybe it messes with iptables manager that is used by the agent to set rules?

Miguel will discuss the issue with Slawek.
