Subject: selftests: mptcp: join: skip Fastclose tests if not supported
From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx>
commit ae947bb2c253ff5f395bb70cb9db8700543bf398 upstream.
Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the support of MP_FASTCLOSE introduced in commit
f284c0c77321 ("mptcp: implement fastclose xmit path").
If the MIB counter is not available, the test cannot be verified and the
behaviour will not be the expected one. So we can skip the test if the
counter is missing.
