DSCP packet marking support in Linuxbridge agent

[OpenStack Infra]

https://review.openstack.org/401458
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.

    DSCP mark value configured by the user in QoS policy.

    DocImpact: DSCP Marking rule support is extended to the
               Linuxbridge L2 agent

    Closes-Bug: #1644369

I checked guides in openstack-manuals repo and neutron-lib repo. There is no info about what drivers are currently supporting DSCP mark rules in QoS so IMO there is nothing to change in docs here.
This "bug" can be closed IMO.

I agree with comment #1 and I didn't find any direct refs to the agent and DSCP other than a generic reference about DSCP in [1].

However to be on the safe side I'm moving to openstack-manuals in case there's a ref or work in progress I'm missing; otherwise it can safely be closed out as invalid IMO.

Other than the above link, there are no refs or WIPs.

Thanks for checking and reporting :)
