This series introduces the ability to control the MPC subflow for
the in kernel PM.

patch 1 && 2 refactor a bit the endpoint lookup and MP_PRIO generation
code, to simplify the next patch.

patch 3 introduces the new feature quering the backup status of the
endpoint used by the MPC subflow and eventually generating the needed
MP_PRIO option.

Patch 4 is a related cleanup.

v1 -> v2:
  - rebased, and omitted old patch 1 which should go through -net

Paolo Abeni (5):
  mptcp: introduce and use mptcp_pm_send_ack()
  mptcp: address lookup improvements
  mptcp: allow the in kernel PM to set MPC subflow priority
  mptcp: more accurate MPC endpoint tracking
  selftests: mptcp: add MPC backup tests

Thanks Paolo, v2 looks good to me.
