pktgen module

[Xiaowei Yang]

Hello list,

I am using 2.6.8 kernel, and would like to use pktgen for a research
project. Although I followed the instruction in pktgen.txt and set the
correct parameters, I was never able to send any packet. I used
tcpdump at the destination machine and didnot receive any
packet. Another labmate also said he was never able to get it work.

Has anyone encountered this problem befor? Or is there something I did
wrong? Attached is the result from cat pg0.
