[PATCH 5.15.y 0/3] mptcp: fix recent failed backports (20250728)

["Matthieu Baerts (NGI0)" <matttbe@kernel.org>]

Greg recently reported 2 patches that could not be applied without
conflicts in v5.15:

 - 37848a456fc3 ("selftests: mptcp: connect: also cover alt modes")
 - fdf0f60a2bb0 ("selftests: mptcp: connect: also cover checksum")

The first one has been resolved by Sasha in [1].

An additional backport was needed to fix issues when running the new
sendfile test:

 - df9e03aec3b1 ("selftests: mptcp: make sendfile selftest work")

Conflicts have been resolved, and documented in each patch.
