Markus Theil 8b4e524dc0 mac80211: mesh: restrict airtime metric to peered established plinks
[ Upstream commit 02a614499600af836137c3fbc4404cd96365fff2 ]

The following warning is triggered every time an unestablished mesh peer
gets dumped. Checks if a peer link is established before retrieving the
airtime link metric.

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.
