Ugh.. Well that's annoying. So, I guess the best option currently with a commodity NIC is to still do the load balancing on the CPU? (with PF_RING or AF_PACKET since that seems to support load balancing now too we don't support it yet though)

In a way since it does include the direct memory injection like the DNA drivers but it also does the multiqueue bidirectional flow based load balancing. I've just been very impressed with the myricom drivers because they're easy to install and start using. We need to make some small changes to broctl to properly support doing the load balancing with the myricom sniffer drivers, but nothing major.
