This is useful and I think we would like to use it here. I have a few questions.

How come the pipeline is set up with metadata instead of a chain of tables
as I presume that would also work?

There are a lot of destination ip addresses. What is the use case this is simulating?
I can't imagine there would be that many mac addresses on the hypervisor unless
it was hosting containers? 

You talk about network virtualization workloads but it doesn’t do any matching on,
for example, vlan vid or vxlan tunnel ID?

This would be quite necessary! Can you give an idea what kind of flows
we should be generating to test it or is it just random ip, mac addresses and l4 ports?
