Long story short, 802.1p provides QoS at layer-2 and DSCP provides QoS at layer-3. Operators may utilize one or both of these in their network infrastructure, so we should ultimately support both of them. However, in comparison to DSCP, end-to-end QoS using 802.1p requires VLAN provider and project/tenant networks. Using VLAN provider networks and overlay project/tenant networks requires mapping 802.1p to DSCP values, likely implementing DSCP on the overlay itself rather than the traffic within it. The most difficult part for both mechanisms... determining the extent of which to expose QoS to projects/tenants.
