From: Franklin S Cooper Jr <redacted> Various CAN or CAN-FD IP may be able to run at a faster rate than what the transceiver the CAN node is connected to. This can lead to unexpected errors. However, CAN transceivers typically have fixed limitations and provide no means to discover these limitations at runtime. Therefore, add support for a can-transceiver node that can be reused by other CAN peripheral drivers to determine for both CAN and CAN-FD what the max bitrate that can be used. If the user tries to configure CAN to pass these maximum bitrates it will throw an error.Please add support to read the maximum bitrate via netlink. Have a look at 12a6075cabc0 ("can: dev: add CAN interface termination API"). I think you need to extend the following functions: can_get_size() and can_fill_info().
Will add in the next version. Thanks, Faiz
