In the commit referred to below we added link tolerance as an additional criteria for declaring broadcast transmission "stale" and resetting the unicast links to the affected node. Unfortunately, this 'improvement' introduced two bugs, which each and one alone cause only limited problems, but combined lead to seemingly stochastic unicast link resets, depending on the amount of broadcast traffic transmitted. The first issue, a missing initialization of the 'tolerance' field of the receiver broadcast link, was recently fixed by commit047491ea33("tipc: set link tolerance correctly in broadcast link"). Ths second issue, where we omit to reset the 'stale_cnt' field of the same link after a 'stale' period is over, leads to this counter accumulating over time, and in the absence of the 'tolerance' criteria leads to the above described symptoms. This commit adds the missing initialization.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
