Following patches will change the way of distributing port object changes from a switchdev operation to a switchdev notifier. The switchdev code currently recursively descends through layers of lower devices, eventually calling the op on a front-panel port device. The notifier will instead be sent referencing the bridge port device, which may be a stacking device that's one of front-panel ports uppers, or a completely unrelated device. rocker currently doesn't support any uppers other than bridge. Thus the only case that a stacked device could be validly referenced by port object notifications are bridge notifications for VLAN objects added to the bridge itself. But the driver explicitly rejects such notifications in rocker_world_port_obj_vlan_add(). It is therefore safe to assume that the only interesting case is that the notification is on a front-panel port netdevice. Subscribe to the blocking notifier chain. In the handler, filter out notifications on any foreign netdevices. Dispatch the new notifiers to rocker_port_obj_add() resp. _del() to maintain the behavior that the switchdev operation based code currently has.

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.
