Subject: [PATCH] selftests: mptcp: diag: skip if MPTCP is not supported

Selftests are supposed to run on any kernels, including the old ones not
supporting MPTCP.

A new check is then added to make sure MPTCP is supported. If not, the
test stops and is marked as "skipped".

[PATCH 5.15.y] selftests: mptcp: diag: skip if MPTCP is not supported

[Matthieu Baerts]

commit 46565acdd29facbf418a11e4a3791b3c8967308d upstream.

  Backport note: a simple conflict with 787eb1e4df93 ("selftests: mptcp:
  uniform 'rndh' variable") where a new line was added for something
  else in the same context.

Selftests are supposed to run on any kernels, including the old ones not
supporting MPTCP.

A new check is then added to make sure MPTCP is supported. If not, the
test stops and is marked as "skipped".
