Dear Nishant,

I used this documentation  
https://doc.dpdk.org/guides/linux_gsg/index.html for Linux.
I also tried to run pktgen using the following guide:  
https://pktgen-dpdk.readthedocs.io/en/latest/
I just wanted to get familiar with the DPDK.
My goal is to have a DPDK platform to evaluate different algorithms  
and also for vSwitches.

I didn't run them simultaneously. I first ran the helloworld and tried  
pktgen but failed in both of them.


Thanks,
Erfan
