Comment 3 Christian Trautman 2016-12-06 15:52:13 UTC 
Verified with openvswitch-2.5.0-22.git20160727.el7fdp.x86_64.rpm

Setup two bridges each with one dpdk port and vhostuser port. 

Nic used was a x520 on numa 1. 

Used real time host and guest. Guest running testpmd as loopback.

Set flow tables accordingly on each switch to direct traffic.

4 PMDs used on host with sched fifo 95, 2 VCpus used inside guest for testpmd PMDs.

Ran 12 hour test running at 4.8 mpps at 0 loss bi directional traffic.
