commitc832962ac9upstream. Whenever bridge driver hits the max capacity of MDBs, it disables the MC processing (by setting corresponding bridge option), but never notifies switchdev about such change (the notifiers are called only upon explicit setting of this option, through the registered netlink interface). This could lead to situation when Software MDB processing gets disabled, but this event never gets offloaded to the underlying Hardware. Fix this by adding a notify message in such case.

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.
