Paolo Abeni says:

====================
mptcp: improve multiple xmit streams support

This series improves MPTCP handling of multiple concurrent
xmit streams.

The to-be-transmitted data is enqueued to a subflow only when
the send window is open, keeping the subflows xmit queue shorter
and allowing for faster switch-over.

The above requires a more accurate msk socket state tracking
and some additional infrastructure to allow pushing the data
pending in the msk xmit queue as soon as the MPTCP's send window
opens (patches 6-10).

As a side effect, the MPTCP socket could enqueue data to subflows
after close() time - to completely spooling the data sitting in the
msk xmit queue. Dealing with the requires some infrastructure and
core TCP changes (patches 1-5)

Finally, patches 11-12 introduce a more accurate tracking of the other
end's receive window.

Overall this refactor the MPTCP xmit path, without introducing
new features - the new code is covered by the existing self-tests.

v2 -> v3:
 - rebased,
 - fixed checkpatch issue in patch 1/13
 - fixed some state tracking issues in patch 8/13

v1 -> v2:
 - this is just a repost, to cope with patchwork issues, no changes
   at all

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
