  Used to retrieve the list of legal Target IDs and LUNs for SCSI devices on a SCSI channel. These
  can either be the list SCSI devices that are actually present on the SCSI channel, or the list of legal
  Target Ids and LUNs for the SCSI channel. Regardless, the caller of this function must probe the
  Target ID and LUN returned to see if a SCSI device is actually present at that location on the SCSI
  channel.

  @param[in]       This    A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.
  @param[in, out]  Target  On input, a pointer to the Target ID (an array of size
                           TARGET_MAX_BYTES) of a SCSI device present on the SCSI channel.
                           On output, a pointer to the Target ID (an array of
                           TARGET_MAX_BYTES) of the next SCSI device present on a SCSI
                           channel. An input value of 0xF(all bytes in the array are 0xF) in the
                           Target array retrieves the Target ID of the first SCSI device present on a
                           SCSI channel.
  @param[in, out]  Lun     On input, a pointer to the LUN of a SCSI device present on the SCSI
                           channel. On output, a pointer to the LUN of the next SCSI device present
