In fact this is the new way

other_config : dpdk-extra: optional string
              Specifies additional eal command line arguments for DPDK.

              The default is empty. Changing this value requires restarting
              the daemon

So it would be something like this before starting ovs with dpdk enabled.
1. follow all you need from http://openvswitch.org/support/dist-docs/INSTALL.DPDK.md.html
2. follow all you need from http://openvswitch.org/support/dist-docs/INSTALL.DPDK-ADVANCED.md.html
3. to fixup the permissions you'd do
   ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-init="--vhost-owner libvirt-qemu:kvm
--vhost-perm 0664"

I'll keep the bug open until I verified that works
