I agree that we should documents impact of Virtio features on traffic
My opinion is that it deserves a dedicated document.

For this PVP doc, I suggest we add a section stating that one could try
with different Virtio features, and in Kevin's result template
proposal, we add a line for Virtio features enabled/disabled.
