VSC7514 is a 10-port switch with 2 extra "CPU ports" (targets in the queuing subsystem for terminating traffic locally). There are 2 issues with hardcoding the CPU port as #10: - It is not clear which snippets of the code are configuring something for one of the CPU ports, and which snippets are just doing something related to the number of physical ports. - Actually any physical port can act as a CPU port connected to an external CPU (in addition to the local CPU). This is called NPI mode (Node Processor Interface) and is the way that the 6-port VSC9959 (Felix) switch is integrated inside NXP LS1028A (the "local management CPU" functionality is not used there). This patch makes it clear that the ocelot_bridge_stp_state_set function operates on the CPU port (by making it an implicit member of the bridging domain), and at the same time adds logic for the NPI port (aka a physical port) to play the role of a CPU port (it shouldn't be part of bridge_fwd_mask, as it's not explicitly enslaved to a bridge).

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.
