makes 'ss -Ml' show mptcp listen sockets.
Iterate over the tcp listen sockets and pick those that have mptcp ulp
info attached.
mptcp_diag_get_info() is modified to prefer msk->first for mptcp sockets
in listen state. This reports accurate number for recv and send queue
(pending / max connection backlog counters).
Sample output:
ss -Mil

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.
