This series is again preliminray work to ease packed ring layout integration. Main changes are using vector buffres also in the dequeue path, and perform IOVA to HVA translation at vectors fill time. I still have to run more benchmarks, but PVP benchmarks does not show performance changes. Good thing is that it saves ~140 further lines.
