Currently mlxsw_sp_port_headroom_init() configures both priomap and buffers by hand. Additionally, for port buffers, it configures buffer 0 with a size that it will never again have if PFC configuration is touched. Rewrite the init code to become a client of the new hdroom code. The only difference in invocation is that the configuration is forced, so that it is issued even if the desired configuration happens to match what is contained in (hitherto not initialized with meaningful values) mlxsw_sp_port->hdroom. Since now mlxsw_sp_port_headroom_init() initializes all the PG buffers to meaningful values, mlxsw_sp_hdroom_configure_buffers() can avoid querying the current configuration, and can fill the whole PBMC itself.

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.
