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.
