I don't think traffic matters all that much, we're talking about control path change. It's more important to exercise all the address lists (l2 unicast, multicast) and rx modes (promisc, allmulti) etc. Then whatever other paths may load to touching the relevant state in the driver (eg virtnet_freeze_down(), not triggers that, suspend?, migration?). In terms of traffic simple ping or a few UDP packets would be enough, mostly to confirm the filtering is working as expected.
