[PATCH net-next 0/5] Misc BPF improvements

This series adds various misc improvements to BPF, f.e. allowing
skb_load_bytes() helper to be used with filter/reuseport programs
to facilitate programming, test cases for program tag, etc. For
details, please see individual patches.

Thanks!

  bpf: simplify __is_valid_access test on cb
  bpf: enable load bytes helper for filter/reuseport progs
  bpf: allow option for setting bpf_l4_csum_replace from scratch
  bpf: add prog tag test case to bpf selftests
