Subject: [PATCH bpf-next 0/4] selftests/bpf: new MPTCP subflow subtest &
 improvements

In this series from Geliang, modifying MPTCP BPF selftests, we have:

- SIGINT support

- A new macro to reduce duplicated code

- A new MPTCP subflow BPF program setting socket options per subflow: it
  looks better to have this old test program in the BPF selftests to
  track regressions and to serve as example.

  Note: Nicolas is no longer working for Tessares, but he did this work
  while working for them, and his email address is no longer available.

- A new MPTCP BPF subtest validating the new BPF program.
