This is a collection of small fixup and minor enhancement patches that have accumulated in the MPTCP tree while net-next was closed. These are prerequisites for larger changes we have queued up.
Patch 1 refines receive buffer autotuning. Patches 2 and 4 are some minor locking and refactoring changes. Patch 3 improves GRO and RX coalescing with MPTCP skbs. Patches 5-7 add a sysctl for tuning ADD_ADDR retransmission timeout, corresponding test code, and documentation. v2: Add sysctl documentation and fix signoff tags.
