The SBCM register configures the shared buffer configuration according to port and TC. So far all pools have had a dynamic size, where the infinite size is easy to express by using max_buff of 0xff. However the MC pool should be configured with static size, and the infinite size thus needs to be set using the field SBCM.infi_max. Therefore add the field infi_max to the SBCM register and to mlxsw_reg_sbcm_pack(). Extend mlxsw_sp_sb_cm_write() to handle infinite sizes as well. Report infinite pool limits as if the limit actually were the total shared buffer size.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
