Subbaraya Sundeep says: ==================== Add ethtool support for completion queue event size After a packet is sent or received by NIC then NIC posts a completion queue event which consists of transmission status (like send success or error) and received status(like pointers to packet fragments). These completion events may also use a ring similar to rx and tx rings. This patchset introduces cqe-size ethtool parameter to modify the size of the completion queue event if NIC hardware has that capability. A bigger completion queue event can have more receive buffer pointers inturn NIC can transfer a bigger frame from wire as long as hardware(MAC) receive frame size limit is not exceeded. Patch 1 adds support setting/getting cqe-size via ethtool -G and ethtool -g. Patch 2 includes octeontx2 driver changes to use completion queue event size set from ethtool -G. ==================== Link: https://lore.kernel.org/r/1645555153-4932-1-git-send-email-sbhatta@marvell.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.
