Subject: [PATCH net 0/3] mptcp: misc. fixes

Here are two unrelated fixes, plus an extra patch:

- Patch 1: prevent a warning by removing an unneeded and incorrect small
  optimisation in the path-manager. A fix for v5.10.

- Patch 2: reset a subflow when MPTCP opts have been dropped after
  having correctly added a new path. A fix for v5.19.

- Patch 3: add a safety check to prevent issues like the one fixed by
  the second patch.
