In CFF flood mode, the way flood vectors are looked up changes: there's a per-FID PGT base, to which a small offset is added depending on type of traffic. Thus each FID occupies a small contiguous block of PGT memory, whereas in the controlled flood mode, flood vectors for a given FID were spread across the PGT. Each FID is associated with one of a handful of profiles. The profile and the traffic type are then used as keys to look up the PGT offset. This offset is then added to the per-FID PGT base. The profile / type / offset mapping needs to be configured by the driver, and is only relevant in CFF flood mode. In this patch, add the SFFP initialization code. Only initialize the one profile currently explicitly used. As follow-up patch add more profiles, this code will pick them up and initialize as well.

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.
