====================
mptcp: improve code coverage and small optimisations

This small series have various unrelated patches:

- Patch 1 and 2: improve code coverage by validating mptcp_diag_dump_one
  thanks to a new tool displaying MPTCP info for a specific token.

- Patch 3: a fix for a commit which is only in net-next.

- Patch 4: reduce parameters for one in-kernel PM helper.

- Patch 5: exit early when processing an ADD_ADDR echo to avoid unneeded
  operations.
