[PATCH net-next 0/4] mptcp: cleanup and improvements in the selftests

[Matthieu Baerts]

This small series of 4 patches adds some improvements in MPTCP
selftests:

- Patch 1 reworks the detailed report of mptcp_join.sh selftest to
  better display what went well or wrong per test.

- Patch 2 adds colours (if supported, forced and/or not disabled) in
  mptcp_join.sh selftest output to help spotting issues.

- Patch 3 modifies an MPTCP selftest tool to interact with the
  path-manager via Netlink to always look for errors if any. This makes
  sure odd behaviours can be seen in the logs and errors can be caught
  later if needed.

- Patch 4 removes stdout and stderr redirections to /dev/null when using
  pm_nl_ctl if no errors are expected in order to log odd behaviours.
