Ido Schimmel says: ==================== mlxsw: Add layer 3 devlink-trap support This patch set from Amit adds support in mlxsw for layer 3 traps that can report drops and exceptions via devlink-trap. In a similar fashion to the existing layer 2 traps, these traps can send packets to the CPU that were not routed as intended by the underlying device. The traps are divided between the two types detailed in devlink-trap documentation: drops and exceptions. Unlike drops, packets received via exception traps are also injected to the kernel's receive path, as they are required for the correct functioning of the control plane. For example, packets trapped due to TTL error must be injected to kernel's receive path for traceroute to work properly. Patch set overview: Patch #1 adds the layer 3 drop traps to devlink along with their documentation. Patch #2 adds support for layer 3 drop traps in mlxsw. Patches #3-#5 add selftests for layer 3 drop traps. Patch #6 adds the layer 3 exception traps to devlink along with their documentation. Patches #7-#9 gradually add support for layer 3 exception traps in mlxsw. Patches #10-#12 add selftests for layer 3 exception traps. ==================== Signed-off-by: David S.

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.
