This series of patches introduces the user device 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. Most of the patches were originally introduced by Stéphane Grosjean and have only been modified slightly. See the following threads for the original patches: * https://lore.kernel.org/linux-can/20220128150157.1222850-1-s.grosjean@xxxxxxxxxxxxxxx/T/#mad8014c9f1c89a50d5944a50ae0a585edec79eab * https://lore.kernel.org/linux-can/20211117150132.37056-1-s.grosjean@xxxxxxxxxxxxxxx/T/#mbf1d7db8433734a1fe08868d79f9927a04fe7ffe Stéphane Grosjean (5): can: peak_usb: rename device_id to a more explicit name can: peak_usb: add callback to read user value of CANFD can: peak_usb: allow flashing of the user device id can: peak_usb: replace unregister_netdev() with can: peak_usb: add ethtool interface to user defined Lukas Magel (2): can: peak_usb: export PCAN user device ID as sysfs device can: peak_usb: align user device id format in log with .../ABI/testing/sysfs-class-net-peak_usb | 15 +++ drivers/net/can/usb/peak_usb/pcan_usb.c | 43 ++++++- drivers/net/can/usb/peak_usb/pcan_usb_core.c | 119 +++++++++++++++++-- drivers/net/can/usb/peak_usb/pcan_usb_core.h | 11 +- drivers/net/can/usb/peak_usb/pcan_usb_fd.c | 64 +++++++++- drivers/net/can/usb/peak_usb/pcan_usb_pro.c | 26 +++- drivers/net/can/usb/peak_usb/pcan_usb_pro.h | 1 + 7 files changed, 254 insertions(+), 25 deletions(-)
