[ovs-discuss] Openvswitch with DPDK issue

[Sundar Ramakrishnan]

Hello,
I am a newbie to this environment and I am unable to find which release of DPDK works fine with Openvswitch. I hope you could enlighten me with some docs or references with which I could build a working setup - 
RHEL 6.6DPDK - 1.7.1OVS - 2.3.1
Following are some steps I figured out from the web & my experiments - 
Error:
