David S. Miller 930a3a6229 Merge branch 'mlxsw-vlan-=vxlan'
mlxsw: Allow 802.1d and .1ad VxLAN bridges to coexist on Spectrum>=2
Ido Schimmel says:

====================
This patchset allows user space to simultaneously configure both 802.1d
and 802.1ad VxLAN bridges on Spectrum-2 and later ASICs. 802.1ad VxLAN
bridges are still forbidden on Spectrum-1.

The reason for the current limitation is that up until now the EtherType
that was pushed to decapsulated VxLAN packets was a property of the
tunnel port, of which there is only one. This meant that a 802.1ad VxLAN
bridge could not be configured if the tunnel port was already configured
to push a 802.1q tag.

This patchset improves the situation by making two changes. First,
decapsulated packets are marked as having their EtherType decided by the
egress port. Second, local ports member in the bridge (e.g., swp1) are
configured to set the correct egress EtherType.

Patchset overview:

Patch #1 adds a register required for the first change

Patches #2-#3 add the register required for the second change and a
corresponding API

Patch #4 prepares the driver for the split in behavior between
Spectrum-1 and later ASICs

Patch #5 performs the two above mentioned changes to allow the driver to
support simultaneous 802.1ad and 802.1d VxLAN bridges on Spectrum-2 and
later ASICs

Patch #6 adds a selftest

Patch #7 removes a selftest that verified the limitation that was lifted
by this patchset

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.
