Hi Members,

I'm facing some problem with testpmd application in dpdk. 

I'm trying to run the testpmd command on a linux. 

But there is no packet counts.

What should I do? Please let me know....

For your understanding, I'll share my log

1. My environment

2. command dpdk-devbind 

3. command testpmd
