Daniel Machon says: ==================== net: sparx5: add support for port mirroring This series adds support for port mirroring, and port mirroring stats, through tc matchall action FLOW_ACTION_MIRRED. The hardware has three independent mirroring probes. Each probe can be configured with a separate set of filtering conditions that must be fulfilled before traffic is mirrored. A mirror probe can have up to 64 source ports and a single monitor port. The direction of a mirror probe determines if rx or tx traffic is mirrored from the source port to the monitor port.

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 reStructuredText 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.
