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".
