Ido Schimmel says: ==================== mlxsw: Refactor parsing configuration The Spectrum ASIC has a configurable limit on how deep into the packet it parses. By default, the limit is 96 bytes. There are several cases where this parsing depth is not enough and there is a need to increase it: Decapsulation of VxLAN packets and timestamping of PTP packets. Currently, parsing depth API is maintained as part of VxLAN module, because the MPRS register which configures parsing depth also configures UDP destination port number used for VxLAN encapsulation and decapsulation. However, in addition to two above mentioned users of this API, the multipath hash code also needs to invoke it in order to correctly hash based on inner fields of IPv6-in-IPv6 packets. Upcoming support for IPv6-in-IPv6 tunneling will add another user, as without increasing the parsing depth such packets cannot be properly decapsulated. Therefore, this patchset refactors the parsing configuration API and moves it out of the VxLAN module to the main driver code. Tested using existing selftests. Patch set overview: Patch #1 adds the new parsing configuration infrastructure. Patch #2 converts existing users to the new infrastructure. Patch #3 deletes the old infrastructure. Patch #4 calls the new infrastructure from the multipath hash code. ==================== 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.
