PGT blocks are allocated through the function mlxsw_sp_pgt_mid_alloc_range(). The interface assumes that the caller knows which piece of PGT exactly they want to get. That was fine while the FID code was the only client allocating blocks of PGT. However for SW-allocated LAG table, there will be an additional client: mlxsw_sp_lag_init(). The interface should therefore be changed to not require particular coordinates, but to take just the requested size, allocate the block wherever, and give back the PGT address. The current FID mode has one place where PGT address can be stored: the FID family's pgt_base. The allocation scheme should therefore be changed from allocating a block per FID flood table, to allocating a block per FID family. Do just that in this patch. The per-family allocation is going to be useful for another related feature as well: the CFF mode.

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.
