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
