[dpdk-users] incorrect tcp checksum on vxlan tunnel

I'm running ovs-dpdk with vxlan tunnel
Setup like http://docs.openvswitch.org/en/latest/howto/userspace-tunneling/

I'm running iperf3 on the endpoints VMs - and I see incorrect TCP checksum at the server side (this is seen after vxlan decap)
I don't think this is ovs-dpdk issue - since the tcp checksum is set in the inner packet (VM payload) , hence should be set by the VM.
Who can assist ?
Best regards
