How to config DPDK compute in OVN

Hi....as far I understand ovs does support dpdk compute to be deployed. I'm referring to the guideline ' *https://docs.openstack.org/networking-ovn/queens/admin/dpdk.html https://docs.openstack.org/networking-ovn/queens/admin/dpdk.html* ' ... It's too brief.. May I know how to config dpdk compute in OVN networking openstack? Hope someone could help what is the config to be done.... Currently compute is run without dpdk over openstack train ovn based. Please need some info on how I can proceed. Thank you
