Here are some various fixes for the MPTCP selftests. Patch 1 fixes a recently modified test to continue to work as expected on older kernels. This is a fix for a recent fix that can be backported up to v5.15. Patch 2 and 3 include dependences when exporting or installing the tests. Two fixes for v6.11-rc1.

But it breaks the test when using old kernels not having commit 86e39e04482b ("mptcp: keep track of local endpoint still available for each msk"), e.g. on v5.15. Similar to commit d4c81bbb8600 ("selftests: mptcp: join: support local endpoint being tracked or not"), it is possible to add the new endpoint conditionally, by checking if "mptcp_pm_subflow_check_next" is present in kallsyms: this is not directly linked to the commit introducing this symbol but for the parent one which is linked anyway. So we can know in advance what will be the expected behaviour, and add the new endpoint only when it makes sense to do so.
