* Pass a command from userspace through to the adapter.
*
* Note that in order to be code-compatible with the Linux
* interface where possible, the formatting of the au_cmd field is
* somewhat Interesting.
*
* For normal commands, the layout is (fields from struct amr_mailbox_ioctl):
*
* 0 mb_command
* 1 mb_channel
* 2 mb_param
* 3 mb_pad[0]
* 4 mb_drive
*
* For SCSI passthrough commands, the layout is:
*
* 0 AMR_CMD_PASS (0x3)
* 1 reserved, 0
* 2 cdb length
* 3 cdb data
* 3+cdb_len passthrough control byte (timeout, ars, islogical)
* 4+cdb_len reserved, 0
* 5+cdb_len channel
* 6+cdb_len target
