Just like MPTCP_PM_ADDR_FLAG_SIGNAL flag is checked in userspace PM
announce mptcp_pm_nl_announce_doit(), PM flags should be checked in
mptcp_pm_nl_subflow_create_doit() too.
If MPTCP_PM_ADDR_FLAG_SUBFLOW flag is not set, there's no flags field
in the output of dump_addr. This looks a bit strange:
id 10 flags 10.0.3.2
This patch uses mptcp_pm_parse_entry() instead of mptcp_pm_parse_addr()
to get the PM flags of the entry and check it. MPTCP_PM_ADDR_FLAG_SIGNAL
flag shouldn't be set here, and if MPTCP_PM_ADDR_FLAG_SUBFLOW flag is
missing from the netlink attribute, always set this flag.

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.
