The OVN Neutron driver and OVN core projects recently added support for SR-IOV. The code has been merged and backported to OSP 16.1 and can be found on the latest composes. We now need to document the feature in OSP. I believe the docs team can leverage the upstream documentation at https://docs.openstack.org/neutron/latest/admin/ovn/sriov.html for its official documentation, The engineering BZ can be found at https://bugzilla.redhat.com/show_bug.cgi?id=1666684
