Changes since v14:
- intrudce bpf_xdp_pointer utility routine and
  bpf_xdp_load_bytes/bpf_xdp_store_bytes helpers
- drop bpf_xdp_adjust_data helper
- drop xdp_frags_truesize in skb_shared_info
- explode bpf_xdp_mb_adjust_tail in bpf_xdp_mb_increase_tail and
  bpf_xdp_mb_shrink_tail

I thought the conclusion of the discussion regarding backward
compatibility was that we should require different program type
or other explicit opt in. Did I misinterpret?

No, you're right. I think we settled on using the 'flags' field instead
of program type, but either way this should be part of the initial patch
set.

ops, right. I will add it in the v16. Sorry for the noise.

Are you fine with bpf_xdp_load_bytes/bpf_xdp_store_bytes proposed solution?

Lorenzo
