Public bug reported:

https://review.openstack.org/347017
Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/neutron" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

commit 8b5d04ff57223885a45dc34e7769a7fd424f7de5
Author: Sławek Kapłoński <slawek@xxxxxxxxxxxx>
Date:   Sat Apr 30 00:53:22 2016 +0200

    Add setting default max_burst value if not given by user
    
    If user will not provide burst value for bandwidth limit rule there is
    need to set such value on appropriate to ensure that bandwith limit
    will work fine.
    To ensure at least proper limitation of TCP traffic we decided to set
    burst as 80% of bw_limit value.
    LinuxBridge agent already sets is like that. This patch add same
    behaviour for QoS extension driver in openvswitch L2 agent.
    
    DocImpact: Add setting default max_burst value in LB and OvS drivers
