What do you mean host to host traffic, is that two VFs on the same host? control plane SWs (such as OVS) don't apply encapsulation within the same host >>>> What about pf-rep? > Are you planning to create a pf-rep too?

We will have pf rep for smartnic schemes where the the pf on the host is not the manager of the eswitch but rather the smartnic driver instance. on non smart env, there are some challenges to address for the pf nic to be fully functional for the slow path (what you described), we will get there down the road if there is a real need.
