[ovn][neutron][ussuri] DPDK support on OVN Openstack? Openstack Doc contradictive Information?

I want to implement DPDK on my Openstack using OVN as mechanism driver. I read 2 documentation: [1] https://docs.openstack.org/neutron/ussuri/admin/ovn/dpdk.html [2] https://docs.openstack.org/neutron/ussuri/admin/config-ovs-dpdk.html In first doc [1], it is said that DPDK has been supported on OVN. But in second doc [2] it is said `The support of this feature is not yet present in ML2 OVN and ODL mechanism drivers.` Which one is true? because I have TCP checksum issue when implement DPDK on OVN same like this: https://bugs.launchpad.net/neutron/+bug/1832021. It has patched on OVS but not work on OVN. Regards,
