Hi Keith. This is a loopback test and I think it somehow affects the performance since there is only one NIC and phy on the mother board.
I tried two mother boards and the tx/rx ( 9611/9497 ) rates look more reasonable. I can also set packet size in pktgen command line. However, I still don't understand why RX Desc 512, TX Desc 1024 are not the same. Should the values suppose to be the same ? Regards- P.T
