networking-odl with ovs-dpdk in devstack

Hello guys,

I am trying to build my devstack with networking-odl and networking-ovs-dpdk both enabled.
Now I am facing some issues that I cannot solve it and I believe the problem would be some errors in my local.conf file.
Since there is no local.conf sample with integrated networking-odl and ovs-dpdk, I tried to integrate local,conf sample from both projects.
Here are my env:
ubuntu 16.04 with kernel 4.4 lowlatency
devstack newton

After running the stack.sh we can start doing our jobs.
I tried to create an instance from webpage and some errors shown.

error from webpage:
 Last exception: Unexpected error while running command. Command: sudo nova-rootwrap /etc/nova/rootwrap.conf ip link set br-int mtu 14
After checking log, I found when we firest bring up devstack, I can see br-int in the system, but after create the instance, netwoking-odl will delete br-int and report this error.

error from q-svc:

Any help would be thanksful, or can someone provide a sample local.conf for both dpdk and networking-odl included?
Thank you.

BR,
