The old pre-CAM DPT driver provided an IOCTL interface that was
implemented in sys/dev/dpt/dpt_control.c, which is commented out in
sys/conf/files presently.
The control devices are named 'dptN' where N is the DPT controller number.
sys/conf/majors:88 dpt DPT RAID Controller <[EMAIL PROTECTED]>
You're going to need to work on dpt_control.c and make it not stomp on the
rest of the driver when it tries to frob the device.
Good luck.
