Comment 4 Christian Trautman 2017-01-18 23:40:39 UTC 
Verified using Jeans reproducer with dpdk 16.11 and ovs 2.6.1
dpdk-16.11-2.el7fdb.x86_64
dpdk-tools-16.11-2.el7fdb.x86_64
openvswitch-2.6.1-3.git20161206.el7fdb.x86_64

Created two hosts with dpdk bond and one vhostuser port. 

Verified each host could receive traffic with macswap testpmd mode inside the guest using a traffic generator connected to the dpdk ports. Then direct connected each hosts NICs for test reproducer.

Setup pktgen on one side and verified traffic would flow with -m "[1/2:3] startup params.

Verified traffic was flowing through second host and no crashes were observed on either side. Also tried other -m core map settings to make sure non caused a crash with the same traffic profile file loaded.
