The mv88e6xxx driver currently assumes a single CPU port in the fabric and thus floods frames with unknown DA on a single DSA port, the one that is one hop closer to the CPU port. With multiple CPU ports in mind, this isn't true anymore because CPU ports could be found behind both DSA ports of a device in-between others. For example in a A <-> B <-> C fabric, both A and C having CPU ports, device B will have to flood such frame to its two DSA ports. This patch considers both CPU and DSA ports of a device as upstream ports, where to flood frames with unknown DA addresses.

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.
