There was architectural problem with how DPDK HQOS was integrated with VPP. It is not native code which can be used at the arbitrary place in the VPP graph. Instead it is hooked to specific dpdk interface. Making it work with per-session QoS will be hard and messy. Having HQoS in VPP will be great addition but it needs to be native code reusable by different features where QoS policy can be applied to subscriber, tunnel, bonding group or physical interface. it probably makes more sense in extending existing policer which is native code in VPP than trying to make DPDK QoS usable with VPP. — Damjan
