Patch 1 removes an unnecessary flag and related code. Patch 2 fixes a bug encountered when closing fallback sockets. Patches 3 and 4 choose a better transmit subflow, with a self test. Patch 5 adjusts tracking of unaccepted subflows Patches 6-8 improve handling of long ADD_ADDR options, with a test. Patch 9 more reliably tracks the MPTCP-level window shared with peers. Patch 10 sends MPTCP-level acknowledgements more aggressively, so the peer can send more data without extra delay.
