From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx> commit 715c78a82e00f848f99ef76e6f6b89216ccba268 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".
