Vladimir Oltean says: ==================== Improvements over DSA conduit ethtool ops DSA interceps 'ethtool -S eth0', where eth0 is the host port of the switch (called 'conduit'). It does this because otherwise there is no way to report port counters for the CPU port, which is a MAC like any other of that switch, except Linux exposes no net_device for it, thus no ethtool hook. Having understood all downsides of this debugging interface, when we need it we needed, so the proposed changes here are to make it more useful by dumping more counters in it: not just the switch CPU port, but all other switch ports in the tree which lack a net_device. Not reinventing any wheel, just putting more output in an existing command. That is patch 3/3. The other 2 are cleanup. ==================== Link: https://patch.msgid.link/20251122112311.138784-1-vladimir.oltean@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 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.
