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-
