There is a desire for the felix driver to gain support for multiple tag_8021q CPU ports, but the current model prevents it. This is because ocelot_apply_bridge_fwd_mask() only takes into consideration whether a port is a tag_8021q CPU port, but not whose CPU port it is. We need a model where we can have a direct affinity between an ocelot port and a tag_8021q CPU port. This serves as the basis for multiple CPU ports. Declare a "dsa_8021q_cpu" backpointer in struct ocelot_port which encodes that affinity. Repurpose the "ocelot_set_dsa_8021q_cpu" API to "ocelot_assign_dsa_8021q_cpu" to express the change of paradigm. Note that this change makes the first practical use of the new ocelot_port->index field in ocelot_port_unassign_dsa_8021q_cpu(), where we need to remove the old tag_8021q CPU port from the reserved VLAN range.

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.
