Petr Machata says: ==================== mlxsw: Add Spectrum-1 ip6gre support Ido Schimmel writes: Currently, mlxsw only supports ip6gre offload on Spectrum-2 and newer ASICs. Spectrum-1 can also offload ip6gre tunnels, but it needs double entry router interfaces (RIFs) for the RIFs representing these tunnels. In addition, the RIF index needs to be even. This is handled in patches #1-#3. The implementation can otherwise be shared between all Spectrum generations. This is handled in patches #4-#5. Patch #6 moves a mlxsw ip6gre selftest to a shared directory, as ip6gre is no longer only supported on Spectrum-2 and newer ASICs. This work is motivated by users that require multiple GRE tunnels that all share the same underlay VRF. Currently, mlxsw only supports decapsulation based on the underlay destination IP (i.e., not taking the GRE key into account), so users need to configure these tunnels with different source IPs and IPv6 addresses are easier to spare than IPv4. Tested using existing ip6gre forwarding selftests. ==================== Link: https://lore.kernel.org/r/cover.1670414573.git.petrm@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

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.
