HDS options(tcp-data-split, hds-thresh) have dependencies between other features like XDP. Basic dependencies are checked in the core API. netdevsim is very useful to check basic dependencies. The default tcp-data-split mode is UNKNOWN but netdevsim driver returns ENABLED when ethtool dumps tcp-data-split mode. The default value of HDS threshold is 0 and the maximum value is 1024. ethtool shows like this. ethtool -g eni1np1 Ring parameters for eni1np1: Pre-set maximums: ... HDS thresh: 1024 Current hardware settings: ... TCP data split: on HDS thresh: 0 ethtool -G eni1np1 tcp-data-split on hds-thresh 1024 ethtool -g eni1np1 Ring parameters for eni1np1: Pre-set maximums: ... HDS thresh: 1024 Current hardware settings: ... TCP data split: on HDS thresh: 1024 Signed-off-by: Taehee Yoo <ap420073@gmail.com> Link: https://patch.msgid.link/20250114142852.3364986-10-ap420073@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

README
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 reStructuredText 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.
