Description
Softnpu currently uses DLPI to transit packets between virtual ASIC ports. DLPI is a packet-at-a-time interface. This results in very slow performance through virtual ASICs and a lot of CPU overhead per packet. We should look for something with better performance. Maybe have softnpu be a virtio producer/consumer?

Research direction
Start by tracing Softnpu's current DLPI packet path and measuring its per-packet CPU and throughput costs. Compare a virtio producer/consumer design with the existing transport; done means the alternatives have been evaluated and a concrete faster approach is selected.
