[ Upstream commit 0353b4a96b7a9f60fe20d1b3ebd4931a4085f91c ] Recently we had an interop issue where RARP packets got suppressed with bridge neigh suppression enabled, but the check in the code was meant to suppress GARP. Exclude RARP packets from it which would allow some VMWare setups to work, to quote the report: "Those RARP packets usually get generated by vMware to notify physical switches when vMotion occurs. vMware may use random sip/tip or just use sip=tip=0. So the RARP packet sometimes get properly flooded by the vtep and other times get dropped by the logic" Reported-by: Amer Abdalamer <amer@nvidia.com> Signed-off-by: Nikolay Aleksandrov <nikolay@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.
