Merge branch 'mptcp-selftest-improvements-and-header-tweak'

Mat Martineau says:

====================
mptcp: Self test improvements and a header tweak

Patch 1 moves a definition to a header so it can be used in a struct
declaration.

Patch 2 adjusts a time threshold for a selftest that runs much slower on
debug kernels (and even more on slow CI infrastructure), to reduce
spurious failures.

Patches 3 & 4 improve userspace PM test coverage.

Patches 5 & 6 clean up output from a test script and selftest helper
tool.
