What makes stateful offload interesting to me is that the final
desintation of a packet is known at RX and can be redirected to a
queue or VF. This allows to build packet batches on shared pages
while preserving the securiy model.

To put this in other words: It is equivalent to applying the snabbswitch
+ vhost-user principle to the kernel but with encap support. The SR-IOV
case would be a further optimization of that.
