Ido Schimmel says: ==================== mlxsw: Shared buffer improvements This patchset includes two improvements with regards to shared buffer configuration in mlxsw. The first part of this patchset forbids the user from performing illegal shared buffer configuration that can result in unnecessary packet loss. In order to better communicate these configuration failures to the user, extack is propagated from devlink towards drivers. This is done in patches #1-#8. The second part of the patchset deals with the shared buffer configuration of the CPU port. When a packet is trapped by the device, it is sent across the PCI bus to the attached host CPU. From the device's perspective, it is as if the packet is transmitted through the CPU port. While testing traffic directed at the CPU it became apparent that for certain packet sizes and certain burst sizes, the current shared buffer configuration of the CPU port is inadequate and results in packet drops. The configuration is adjusted by patches #9-#14 that create two new pools - ingress & egress - which are dedicated for CPU traffic. ==================== Acked-by: Jakub Kicinski <jakub.kicinski@netronome.com> 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.
