Upon reception of the NETDEV_CHANGEUPPER, a leaving port is already unbridged, so reflect this by assigning the port's bridge_dev pointer to NULL before calling the port_bridge_leave DSA driver operation. Now that the bridge_dev pointer is exposed to the drivers, reflecting the current state of the DSA switch fabric is necessary for the drivers to adjust their port based VLANs correctly. Pass the bridge device pointer to the port_bridge_leave operation so that drivers have all information to re-program their chips properly, and do not need to cache it anymore.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
