You seem to be using that patch of yours where you route to yourself?
Well, since you are up for it:
- try with two ports only; eth0->eth1 and vary then vary RX ring
{32, 64,128,256,512,1024}
- send at least 1 minute worth of data at wire rate
a) small packets 64 bytes
b) repeat with MTU sized packets

Repeat above with eth0->eth1, eth2->eth3

also try where machine is a router and you have a source/sink host

cheers,
