That's the ioctl visible to userland.  To support it, you have to add 
an ioctl handler to the HBA driver.

If every HBA driver has an ioctl handler just to do this, why not make 
the generic scsibus ioctl handler do it, and make the adapter drivers 
use a new command in their already existing "adapter_request" entry 
points...
