Thanks for that. So its showing ~ 600k pps throughput. I'd love to
know whats setting that upper limit - is it iperf? Userspace?
Interrupt thread/device driver? Other kernel stuff?

This is just a curiousity for me at the moment. I hear people
occasionally using 10GE cards in Linux/FreeBSD setups as routers and
I'm interested in how the degenerate case performs.
