* The library routine dcd_probe() is provided as a service to target

* defined as:
*
* int dcd_probe(struct scsi_device *devp, int (*callback()))
*
* dcd_probe() only executes an inquiry.
*
* Both functions return one of the integer values as defined below:

* The following are the defines for the dcd_options. The dcd_options

* The following is the layout of the dcd_options bit.
*
* Bit 0, 1, 2, 3, 4 - Indicate the mode that is requested.
* Bit 5 represent the support for Ultra ATA.
* Bit 6 represent the support for Block Mode.
* Bit 7 will indicate PIO or DMA (set means DMA).
