Subject: [PATCH net-next 0/5] mptcp: Support changes to initial subflow priority

This series updates the in-kernel MPTCP path manager to allow changes to
subflow priority for the first subflow created for each MPTCP connection
(the one created with the MP_CAPABLE handshake).

Patches 1 and 2 do some refactoring to simplify the new functionality.

Patch 3 introduces the new feature to change the initial subflow
priority and send the MP_PRIO header on that subflow.

Patch 4 cleans up code related to tracking endpoint ids on the initial
subflow.

Patch 5 adds a selftest to confirm that subflow priorities are updated
as expected.

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
