Stefan Chulski 73445f2957 net: mvpp2: Add TCAM entry to drop flow control pause frames
[ Upstream commit 3f48fab62bb81a7f9d01e9d43c40395fad011dd5 ]

Issue:
Flow control frame used to pause GoP(MAC) was delivered to the CPU
and created a load on the CPU. Since XOFF/XON frames are used only
by MAC, these frames should be dropped inside MAC.

Fix:
According to 802.3-2012 - IEEE Standard for Ethernet pause frame
has unique destination MAC address 01-80-C2-00-00-01.
Add TCAM parser entry to track and drop pause frames by destination MAC.

README

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.
