In expectation of the new tag_ocelot_8021q tagger implementation, we need to be able to do runtime switchover between one tagger and another. So we must structure the existing code for the current NPI-based tagger in a certain way. We move the felix_npi_port_init function in expectation of the future driver configuration necessary for tag_ocelot_8021q: we would like to not have the NPI-related bits interspersed with the tag_8021q bits. The conversion from this: ocelot_write_rix(ocelot, ANA_PGID_PGID_PGID(GENMASK(ocelot->num_phys_ports, 0)), ANA_PGID_PGID, PGID_UC); to this: cpu_flood = ANA_PGID_PGID_PGID(BIT(ocelot->num_phys_ports)); ocelot_rmw_rix(ocelot, cpu_flood, cpu_flood, ANA_PGID_PGID, PGID_UC); is perhaps non-trivial, but is nonetheless non-functional. The PGID_UC (replicator for unknown unicast) is already configured out of hardware reset to flood to all ports except ocelot->num_phys_ports (the CPU port module). All we change is that we use a read-modify-write to only add the CPU port module to the unknown unicast replicator, as opposed to doing a full write to the register.

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.
