From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx> commit 46565acdd29facbf418a11e4a3791b3c8967308d upstream. 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".
