CFF mode, for Compressed FID Flooding, is a way of organizing flood vectors in the PGT table. The bus module determines whether CFF is supported, can configure flood mode to CFF if it is, and knows what flood mode has been configured. Therefore add a bus callback to determine the configured flood mode. Also add to core an API to query it. Since after this patch, we rely on mlxsw_pci->flood_mode being set, it becomes a coding error if a driver invokes this function with a set of fields that misses the initialization. Warn and bail out in that case. The CFF mode is not used as of this patch. The code to actually use it will be added later.

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.
