Selftests are supposed to run on any kernels, including the old ones not supporting all MPTCP features. One of them is the getsockopt(SOL_MPTCP) to get info about the MPTCP connections introduced by commit 55c42fa7fa33 ("mptcp: add MPTCP_INFO getsockopt") and the following ones. It is possible to look for "mptcp_diag_fill_info" in kallsyms because it is introduced by the mentioned feature. So we can know in advance if the feature is supported and skip the sub-test if not.
