Linux kernel source tree

ocelot_fdb_add() redirects FDB entries installed on the NPI port towards the special reserved PGID_CPU used for host-filtered addresses. PGID_CPU contains BIT(ocelot->num_phys_ports) in the destination port mask, which is code name for the CPU port module. Whereas felix_migrate_fdbs_to_*_port() uses the ocelot->num_phys_ports PGID directly, and it appears that this works too. Even if this PGID is set to zero, apparently its number is special and packets still reach the CPU port module. Nonetheless, in the end, these addresses end up in the same place regardless of whether they go through an extra indirection layer or not. Use PGID_CPU across to have more uniformity.

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.
