Lukas Magel <lukas.magel@posteo.net> says: This series of patches introduces the CAN channel ID for the PEAK USB CAN interfaces. The id can be read/written via ethtool and is exposed as a read-only attribute via sysfs. This allows users to set the id via ethtool and write udev rules to match against the sysfs attribute. Part of the patches were originally introduced by Stéphane Grosjean and were modified slightly. See the following threads for the original patches: * https://lore.kernel.org/linux-can/20220128150157.1222850-1-s.grosjean@peak-system.com * https://lore.kernel.org/linux-can/20211117150132.37056-1-s.grosjean@peak-system.com changes since v2: https://lore.kernel.org/all/20221030105939.87658-1-lukas.magel@posteo.net * Fix the issues raised on netdev * Rename user device ID to CAN channel ID to make the 1-to-N mapping between USB device and exposed CAN channels more obvious changes since v1: https://lore.kernel.org/all/20221022213535.8495-1-lukas.magel@posteo.net * Fix type of devid_le in ethtool peak_usb_(get|set)_eeprom * Fix signed-off tags Link: https://lore.kernel.org/all/20221213080309.9013-1-lukas.magel@posteo.net [mkl: added links] Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
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.
