Yotam Gigi 98d0f7b9ac mlxsw: spectrum: Add packet sample offloading support
Using the MPSC register, add the functions that configure port-based
packet sampling in hardware and the necessary datatypes in the
mlxsw_sp_port struct. In addition, add the necessary trap for sampled
packets and integrate with matchall offloading to allow offloading of the
sample tc action.

The current offload support is for the tc command:

tc filter add dev <DEV> parent ffff: \
	  matchall skip_sw \
	  action sample rate <RATE> group <GROUP> [trunc <SIZE>]

Where only ingress qdiscs are supported, and only a combination of
matchall classifier and sample action will lead to activating hardware
packet sampling.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

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.
