From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx> commit 0f4955a40dafe18a1122e3714d8173e4b018e869 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".
