The bnxt_en driver has configured the hds_threshold value automatically when TPA is enabled based on the rx-copybreak default value. Now the hds-thresh ethtool command is added, so it adds an implementation of hds-thresh option. Configuration of the hds-thresh is applied only when the tcp-data-split is enabled. The default value of hds-thresh is 256, which is the default value of rx-copybreak, which used to be the hds_thresh value. The maximum hds-thresh is 1023. # Example: # ethtool -G enp14s0f0np0 tcp-data-split on hds-thresh 256 # ethtool -g enp14s0f0np0 Ring parameters for enp14s0f0np0: Pre-set maximums: ... HDS thresh: 1023 Current hardware settings: ... TCP data split: on HDS thresh: 256 Tested-by: Stanislav Fomichev <sdf@fomichev.me> Tested-by: Andy Gospodarek <gospo@broadcom.com> Signed-off-by: Taehee Yoo <ap420073@gmail.com> Reviewed-by: Michael Chan <michael.chan@broadcom.com> Link: https://patch.msgid.link/20250114142852.3364986-9-ap420073@gmail.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 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.
