Patch 1 adds a configurable timeout for the MPTCP connection when all
subflows are closed, to support break-before-make use cases.
Patch 2 is a fix for a 1-byte error in rx data counters with MPTCP
fastopen connections.
Patch 3 is a minor code cleanup.
Patches 4 & 5 add handling of rcvlowat for MPTCP sockets, with a
prerequisite patch to use a common scaling ratio between TCP and MPTCP.
Patch 6 improves efficiency of memory copying in MPTCP transmit code.
Patch 7 refactors syncing of socket options from the MPTCP socket to
its subflows.
Patches 8 & 9 help the MPTCP packet scheduler perform well by changing
the handling of notsent_lowat in subflows and how available buffer space
is calculated for MPTCP-level sends.
