When packets are mirrored to the CPU, the trap identifier with which the packets are trapped is determined according to the session identifier of the SPAN agent performing the mirroring. Packets that are trapped for the same logical reason (e.g., buffer drops) should use the same session identifier. Currently, a single session is implicitly supported (identifier 0) and is used for packets that are mirrored to the CPU due to buffer drops (e.g., early drop). Subsequent patches are going to mirror packets to the CPU due to sampling, which will require a different session identifier. Prepare for that by making the session identifier an attribute of the SPAN agent. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Signed-off-by: David S.

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.
