Currently, mlxsw assumes that each ingress pool has its egress counterpart, and that pool index for purposes of caching matches the index with which the hardware should be configured. As we want to expose the MC pool, both of these assumptions break. Instead, maintain the pool index as long as possible. Unify ingress and egress caches and use the pool index as cache index as well. Only translate to FW pool numbering when actually packing the registers. This simplifies things considerably, as the pool index is the only quantity necessary to uniquely identify a pool, and the pool/direction split is not necessary until firmware is talked to. To support the mapping between pool indices and pool numbers and directions, which is not neatly mathematical anymore, introduce a pool descriptor table, indexed by pool index, to facilitate the translation. Include the MC pool in the descriptor table as well, so that it can be referenced from mlxsw_sp_sb_cms_egress.

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.
