Paolo Abeni 218cc16632 selftests: mptcp: avoid spurious errors on disconnect
The disconnect test-case generates spurious errors:

  INFO: disconnect
  INFO: extra options: -I 3 -i /tmp/tmp.r43niviyoI
  01 ns1 MPTCP -> ns1 (10.0.1.1:10000      ) MPTCP (duration 140ms) [FAIL]

  04 ns1 TCP   -> ns1 (dead:beef:1::1:10003) MPTCP (duration  26ms) [ OK ]
  [FAIL] Tests of the full disconnection have failed
  Time: 2 seconds

The root cause is actually in the user-space bits: the test program
currently disconnects as soon as all the pending data has been spooled,
generating an FASTCLOSE. If such option reaches the peer before the
latter has reached the closed status, the msk socket will report an
error to the user-space, as per protocol specification, causing the
above failure.

Address the issue explicitly waiting for all the relevant sockets to
reach a closed status before performing the disconnect.

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 reStructuredText 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.
