Here are some patches we've merged in the MPTCP tree that are ready for net-next.
Patches 1 and 2 rework the assignment of local address IDs to allow them to be assigned by a userspace path manager, and add corresponding self tests. Patches 2-8 add the ability to change subflow priority after a subflow has been established. Each subflow in a MPTCP connection has a priority level: "regular" or "backup". Data should only be sent on backup subflows if no regular subflows are available. The priority level can be set when the subflow connection is established (as was already implemented), or during the life of the connection by sending MP_PRIO in the TCP options (as added here). Self tests are included.
