This test runs two streams of traffic from two independent ports to create congestion on one egress port. It is necessary to configure the shared buffer thresholds correctly, to make sure that there is traffic from both streams in the shared buffer. Only then can the test actually test prioritization among these streams. Without this configuration, it is possible, that one of the streams takes all of port-pool quota, and the other stream is not even admitted, thus invalidating the result. On Spectrum-1, this is not a problem, because MC traffic uses a separate pool. But for Spectrum-2, MC and UC share the same pool, and the correct configuration is important.

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.
