OT: In Cilium we run similar NAT46/64 translation for XDP and tc/BPF for our LB services [4] (that is, v4 VIP with v6 backends, and v6 VIP with v4 backends).

It is complicated for me, my case doesnot use XDP driver.I use xdp_dummy just to enable veth NAPI GRO, not real XDP driver code. My test case is simple and enough for my patch, I think. I have covered tcp and udp, normal and SO_SEGMENT.
Ok, fair enough, then lets resend with the minor fixups as discussed earlier and worst case we can do the test_progs integration at a later point to avoid blocking the fix. At least there is something runnable under net/bpf selftests.. even if not yet in BPF CI but we can follow-up on it later. Thanks Lina!
