The problem appears to be outside ovs. Somewhere you wrote that you are using a physical switch. Could you remove that and connect the outside PC directly to the dpdk port?
If things still do not work, I would suggest to use the test_pmd ( http://dpdk.org/doc/guides/testpmd_app_ug/index.html) application to test your card. Once again, please let me know the results.
