Subject: selftests: mptcp: pm nl: skip fullmesh flag checks if not supported
From: Matthieu Baerts <matthieu.baerts@xxxxxxxxxxxx>
commit f3761b50b8e4cb4807b5d41e02144c8c8a0f2512 upstream.
Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the fullmesh flag that can be given to the MPTCP
in-kernel path-manager and introduced in commit 2843ff6f36db ("mptcp:
remote addresses fullmesh").
If the flag is not visible in the dump after having set it, we don't
check the content. Note that if we expect to have this feature and
SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var is set to 1, we always
check the content to avoid regressions.
