FID code reserves about 15K entries in PGT table for flooding. These entries are just allocated and are not used yet because the code that uses them is skipped now. The next patches will convert MDB code to use PGT APIs. The allocation of indexes for multicast is done after FID code reserves 15K entries. Currently, legacy bridge model is used and firmware manages PGT table. That means that the indexes which are allocated using PGT API are too high when legacy bridge model is used. To not exceed firmware limitation for MDB entries, add an API that returns the correct 'mid_index', based on bridge model. For legacy model, subtract the number of flood entries from PGT index. Use it to write the correct MID to SMID register. This API will be used also from MDB code in the next patches. PGT should not be aware of MDB and FID different usage, this API is temporary and will be removed once unified bridge model will be used.

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.
