tail_nodeport_nat_egress_ipv4() doesn't have any support for XDP passthrough yet. See encap_geneve_dsr_opt4() for what would be needed to rewrite the outer headers. We also haven't considered how the reply traffic for non-DSR connections would get handled in the LB. Therefore limit the encap-detection to full-DSR.
