PGT, a port-group table is an in-HW block of specialized memory that holds sets of ports. Allocated within the PGT are series of flood tables that describe to which ports traffic of various types (unknown UC, BC, MC) should be flooded from which FID. The hitherto-used layout of these flood tables is being replaced with a more flexible scheme, called compressed FID flooding (CFF). CFF can be configured through CONFIG_PROFILE.flood_mode. cff_support determines whether CONFIG_PROFILE.flood_mode can be set to CFF.

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.
