The port headroom handling is currently strewn across several modules and tricky to follow: MTU, DCB PFC, DCB ETS and ethtool pause all influence the settings, and then there is the completely separate initial configuraion in spectrum_buffers. A following patch will implement the dcbnl_setbuffer callback, which is going to further complicate the landscape. In order to simplify work with port buffers, the following patches are going to centralize all port-buffer handling in spectrum_buffers. As a first step, introduce a (currently empty) struct mlxsw_sp_hdroom that will keep the configuration parameters, and allocate and free it in appropriate places.

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.
