Linux kernel source tree
5be3637e06
Some pools configured through the sb_pm entries may have by default static size. The MC pool is now not explicitly configured, however it gets configured as static implicitly by 0-initializing sb->prs, and a follow-up patch adds an explicit configuration to the same effect. To support this, pass max_buff taken from sb_pm and sb_cm entries through cell conversion before handing it to mlxsw_sp_sb_pm_write(), if the pool that the sb_pm entry configures is statically-sized. To keep current behavior, update mlxsw_sp_sb_cms_egress[] to denote buffer sizes in bytes (assuming Spectrum 1 cell sizes, which the original code assumed as well) instead of cells. Note that a follow-up patch changes this to infinite size. Also tweak a comment at SBMM configuration to remain true now that statically-sized pools exist.

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.
