testpmd_pvp: Adds pkt_fwd to allow pvp topology testing
Requires DPDK 16.11 or greater to support vdev flags. Initial support for TestPMD to support guests. Allows vsperf to execute TestPMD as a switch for pvp test scenarios. Can be increased in functionality later to support multiple guest configs. JIRA: VSPERF-406 Change-Id: I67a5a355c990ca6cfcbb5845a2beaf1c1f21f5f0 Signed-off-by: Christian Trautman <ctrautma@redhat.com>
