72 * Pass a command from userspace through to the adapter.

74 * Note that in order to be code-compatible with the Linux

76 * somewhat Interesting.

78 * For normal commands, the layout is (fields from struct amr_mailbox_ioctl):

80 * 0 mb_command
81 * 1 mb_channel
82 * 2 mb_param
83 * 3 mb_pad[0]
84 * 4 mb_drive

86 * For SCSI passthrough commands, the layout is:

88 * 0 AMR_CMD_PASS (0x3)
89 * 1 reserved, 0
90 * 2 cdb length
91 * 3 cdb data
92 * 3+cdb_len passthrough control byte (timeout, ars, islogical)
