Public bug reported:

If user will set QoS bw_limit rule without giving burst value (or this burst is set to 0kb) then bw limit could not work properly. We should change openvswitch QoS driver to set min burst value as 80 % of configured bw_limit. 80% is value which should works fine for TCP traffic.
Such change will make consistent behaviour between Linuxbridge agent and openvswitch agent. See on https://launchpad.net/bugs/1563720 for LB implementation details.
