Matthieu Baerts (NGI0) 9d1f4ecc31 selftests: mptcp: join: check backup support in signal endp 
commit f833470c27 upstream.

Before the previous commit, 'signal' endpoints with the 'backup' flag
were ignored when sending the MP_JOIN.

The MPTCP Join selftest has then been modified to validate this case:
the "single address, backup" test, is now validating the MP_JOIN with a
backup flag as it is what we expect it to do with such name. The
previous version has been kept, but renamed to "single address, switch
to backup" to avoid confusions.

The "single address with port, backup" test is also now validating the
MPJ with a backup flag, which makes more sense than checking the switch
to backup with an MP_PRIO.

The "mpc backup both sides" test is now validating that the backup flag
is also set in MP_JOIN from and to the addresses used in the initial
subflow, using the special ID 0.

The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

[ Conflicts in mptcp_join.sh because 'run_tests' helper has been
  modified in multiple commits that are not in this version, e.g. commit
  e571fb09c8 ("selftests: mptcp: add speed env var") and commit
  ae7bd9ccec ("selftests: mptcp: join: option to execute specific
  tests"). Adaptations have been made to use the old way, similar to
  what is done around.
  Also in this version, there is no "single address with port, backup"
  subtest. Same for "mpc backup both sides". ]

README 

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.
