A so-called "MC-aware" mode has recently been enabled in mlxsw. In MC-aware mode, BUM traffic is handled in a special way so that when a switch is flooded with BUM, UC performance isn't unduly impacted. Without enablement of this mode, a stream of BUM traffic can cause sustained UC throughput drop in excess of 99 %. Add a test for this behavior. Compare how much UC throughput degrades as a stream of broadcast frames floods the switch. A minimal degradation is tolerated to cover for glitches in traffic injection performance.

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.
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.
