Dear DPDK experts.
 
Thank you very much for your best great efforts and precious answers.
 
I have a problem in setting up DPDK 2.1.0 in Fedora OS release 20 (Heisenbug).
 
My problem is that I cannot receive any traffics in test-pmd.
 
There are 2 nics (2 port NIC), I connected port 0 to port 1(loopback), port 2 to port3 (loopback).
 
I attached details of my setup. I also attached my DPDK setup shell script.
 
Did I miss something? or Is there any my mistakes?
 
 
I will really appreciate if you check them and I can be given any advice and answers.
 
 
It is important for me and urgent job.
 
Thank you very much.
 
Sincerely Yours,
 
Ick-Sung Choi.
