Spectrum-2 and later ASICs support sampling of packets by mirroring to the CPU with probability. There are several advantages compared to the legacy dedicated sampling mechanism: * Extra metadata per-packet: Egress port, egress traffic class, traffic class occupancy and end-to-end latency * Ability to sample packets on egress / per-flow Convert Spectrum-2 and later ASICs to perform sampling by mirroring to the CPU with probability. Subsequent patches will add support for egress / per-flow sampling and expose the extra metadata.

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.
