Ido Schimmel says: ==================== mlxsw: Add support for IP-in-IP with IPv6 underlay Currently, mlxsw only supports IP-in-IP with IPv4 underlay. Traffic routed through 'gre' netdevs is encapsulated with IPv4 and GRE headers. Similarly, incoming IPv4 GRE packets are decapsulated and routed in the overlay VRF (which can be the same as the underlay VRF). This patchset adds support for IPv6 underlay using the 'ip6gre' netdev. Due to architectural differences between Spectrum-1 and later ASICs, this functionality is only supported on Spectrum-2 onwards (the software data path is used for Spectrum-1). Patchset overview: Patches #1-#5 are preparations. Patches #6-#9 add and extend required device registers. Patches #10-#14 gradually add IPv6 underlay support. A follow-up patchset will add net/forwarding/ selftests. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
