[RFE] Qos DSCP to vlan priority mapping

[Na Zhu]

[Background]
In N release, Qos already support DSCP marking, and the RFE about supporting 802.1q already confirmed.
https://bugs.launchpad.net/neutron/+bug/1505631

[Proposal]
vlan 802.1q support Qos at layer-2, it is necessary for the scenario that physical devices only support L2. In NFV, there are many kinds of IP traffic, it is necessary to provide preferential treatment to certain types of traffic at the expense of others, different priority traffic have different DSCP, the ovs mapping DSCP to vlan priority, and the physical device do QOS based on vlan priority.
DSCP to vlan priority mapping is useful in NFV environment.

needs feedback from someone more familiar with qos to see feasibility for Newton

[Miguel Angel Ajo (mangelajo)]

Do you mean, you want to translate instance generated DSCP flags into VLAN q pcp/dei fields? ,

Or that you want policy rules setting DSCP flags, to be also translated to VLAN Q?

If you want the pcp / dei fields set on VLANq, there's another RFE for that.
