Problem when testing ovs-dpdk

[DucHoangManh]

After creating pod, with following mount folder:
(I tried to set the shared-dir to /var/run/openvswitch/unique_directory but got the error Rename ERROR:... invalid cross-device link so, I use the default folder for testing purpose)

    - mountPath: /vhu
      name: shared-dir
volumes:
  - name: shared-dir
    hostPath:
      path: /var/run/openvswitch/

I see the socket files show up in /var/run/openvswitch/, but when testing with testpmd, its always showing 0 statistic. I don't know how to fix this..
