you should consider moving to a more modern nic model: igb, which has sr-iov support too.

yes, can do. with igb i see multiple irqs, so test will have to take sum of all rx irqs, and compare:

I feel e1000e suffices for this test, should i stay with e1000e or use igb here ?

or use a single cpu per socket config. Which seems better for the test.

The test uses single cpu per socket, since i have `-smp 4,sockets=4,threads=1`. Was this what you meant ?

yes. or cores=1, as you wish.

sure, will add cores=1 for clarity.

do you have any further comments before i send a v4 with this change, and #include's removed ?

It looked ok. Thanks, C.
