In the case where the driver asks for a replay of a certain type of event (port object or attribute) for a bridge port that is a LAG, it may do so because this port has just joined the LAG. But there might already be other switchdev ports in that LAG, and it is preferable that those preexisting switchdev ports do not act upon the replayed event. The solution is to add a context to switchdev events, which is NULL most of the time (when the bridge layer initiates the call) but which can be set to a value controlled by the switchdev driver when a replay is requested. The driver can then check the context to figure out if all ports within the LAG should act upon the switchdev event, or just the ones that match the context. We have to modify all switchdev_handle_* helper functions as well as the prototypes in the drivers that use these helpers too, because these helpers hide the underlying struct switchdev_notifier_info from us and there is no way to retrieve the context otherwise. The context structure will be populated and used in later patches.

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.
