OVS does both, depending on whether the DF bit is set. OVN does neither in all tests that I have performed, I also haven't seen any change when enabling "ovn_emit_need_to_frag".

I have created https://review.opendev.org/c/openstack/neutron/+/892839 in order to at least document these deficiencies.
