Subject: [PATCH bpf-next v2 0/2] selftests/bpf: new MPTCP subflow subtest

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

- 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 this new BPF program.

Changes in v2:
- Previous patches 1/4 and 2/4 have been dropped from this series:
  - 1/4: "selftests/bpf: Handle SIGINT when creating netns":
    - A new version, more generic and no longer specific to MPTCP BPF
      selftest will be sent later, as part of a new series. (Alexei)
  - 2/4: "selftests/bpf: Add RUN_MPTCP_TEST macro":
    - Removed, not to hide helper functions in macros. (Alexei)
- The commit message of patch 1/2 has been clarified to avoid some
  possible confusions spot by Alexei.
- Link to v1: https://lore.kernel.org/r/20240507-upstream-bpf-next-20240506-mptcp-subflow-test-v1-0-e2bcbdf49857@kernel.org
