Camelia Groza says: ==================== dpaa_eth: A050385 erratum workaround fixes under XDP This series addresses issue with the current workaround for the A050385 erratum in XDP scenarios. The first patch makes sure the xdp_frame structure stored at the start of new buffers isn't overwritten. The second patch decreases the required data alignment value, thus preventing unnecessary realignments. The third patch moves the data in place to align it, instead of allocating a new buffer for each frame that breaks the alignment rules, thus bringing an up to 40% performance increase. With this change, the impact of the erratum workaround is reduced in many cases to a single digit decrease, and to lower double digits in single flow scenarios. Changes in v2: - guarantee enough tailroom is available for the shared_info in 1/3 ==================== Link: https://lore.kernel.org/r/cover.1612456902.git.camelia.groza@nxp.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.
