[PATCH net-next 0/7] selftests: mptcp: increase code coverage

[Matthieu Baerts (NGI0)]

Here are various patches slightly improving MPTCP code coverage:

- Patch 1: avoid a harmless 'grep: write error' warning.

- Patch 2: use getaddrinfo() with IPPROTO_MPTCP in more places.

- Patch 3-6: prepare and add support to get info for a specific subflow
  when giving the 5-tuple.

- Patch 7: validate the previous patch and cover "subflow_get_info_size"
  in the kernel code (mptcp_diag.c).
