Yes, we will add the description. Thanks.

Yes, this is already implemented, although not used for CTU CAN FD at
the moment. IOCTL calls not recognized by common layer in can-bus.c are
passed to the driver (if driver implements this functionality, otherwise
-EINVAL is returned immediately). So it is possible for driver to have
specific IOCTL calls.
