Bug Description

Currently QoS is supported by openvswitch agent (QosOVSAgentDriver) and by sr-iov agent (QosSRIOVAgentDriver) on compute hosts.
There should be also similar agent for support LinuxBridge agent. It can set bw limitations using "tc" which can be applied for ingress and egress traffic on different ports (interfaces) in linux bridge.

Correct, you don't need to create a new agent, just integrate the agent extensions in the linuxbridge agent :)

There is nobody assigned to this bug. Can I get this if nobody will propose this feature?

I see no reason why linuxbridge would be second class compared to OVS, as matter of fact it isn't so I am happy to see this happening. That said, please identify a person who can help you in the review process. Is that going to be Ihar?

related to http://lists.openstack.org/pipermail/openstack-dev/2016-February/087360.html , shall we slam this to a simple bug?, This is not an RFE imo.

    Add support for QoS for LinuxBridge agent

    There is a new QoS extension driver for the linuxbridge agent

    on the linuxbridge agent.
    This patch introduces two new config options for Linuxbridge agent:
    kernel_hz - HZ value of host kernel,
    tbf_latency - value of latency in tbf qdisc to calculate size of queue.
