Amit Cohen 6d627a29aa mlxsw: Trap ARP packets at layer 2 instead of layer 3
Next patch will set the same hardware domain for all bridge ports,
including VXLAN, to prevent packets from being forwarded by software when
they were already forwarded by hardware.

ARP packets are not flooded by hardware to VXLAN, so software should handle
such flooding. When hardware domain of VXLAN device will be changed, ARP
packets which are trapped and marked with offload_fwd_mark will not be
flooded to VXLAN also in software, which will break VXLAN traffic.

To prevent such breaking, trap ARP packets at layer 2 and don't mark them
as L2-forwarded in hardware, then flooding ARP packets will be done only
in software, and VXLAN will send ARP packets.

Remove NVE_ENCAP_ARP which is no longer needed, as now ARP packets are
trapped when they enter the device.

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 reStructuredText 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.
