bridge: FDB: Notify about removal of non-user-added entries
Device drivers may generally need to keep in sync with bridge's FDB. In
particular, for its offload of tc mirror action where the mirrored-to
device is a gretap device, mlxsw needs to listen to a number of events,
FDB events among the others. SWITCHDEV_FDB_{ADD,DEL}_TO_DEVICE would be
a natural notification in that case.
However, for removal of FDB entries added due to device activity (as
opposed to explicit addition through "bridge fdb add" or similar), there
are no notifications.
Thus in patch #1, add the "added_by_user" field to switchdev
notifications sent for FDB activity. Adapt drivers to ignore activity on
non-user-added entries, to maintain the current behavior. Specifically
in case of mlxsw, allow mlxsw_sp_span_respin() call for any and all FDB
updates.
In patch #2, change the bridge driver to actually emit notifications for
these FDB entries. Take care not to send notification for bridge
updates that itself originate in SWITCHDEV_FDB_*_TO_BRIDGE events.
Changes from v1 to v2:
- Instead of introducing a new variant of fdb_delete(), add a new
parameter to the existing function.
- Name the parameter swdev_notify, not notify.

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.
