  90   Sends a SCSI Request Packet to a SCSI device that is attached to the SCSI channel. This function
  91   supports both blocking I/O and nonblocking I/O. The blocking I/O functionality is required, and the

  93
  94   @param  This    A pointer to the EFI_EXT_SCSI_PASS_THRU_PROTOCOL instance.
  95   @param  Target  The Target is an array of size TARGET_MAX_BYTES and it represents
  96                   the id of the SCSI device to send the SCSI Request Packet. Each
  97                   transport driver may chose to utilize a subset of this size to suit the needs
  98                   of transport target representation. For example, a Fibre Channel driver
  99                   may use only 8 bytes (WWN) to represent an FC target.
 100   @param  Lun     The LUN of the SCSI device to send the SCSI Request Packet.
 101   @param  Packet  A pointer to the SCSI Request Packet to send to the SCSI device
 102                   specified by Target and Lun.
 103   @param  Event   If nonblocking I/O is not supported then Event is ignored, and blocking
 104                   I/O is performed. If Event is NULL, then blocking I/O is performed. If
 105                   Event is not NULL and non blocking I/O is supported, then
 106                   nonblocking I/O is performed, and Event will be signaled when the
 107                   SCSI Request Packet completes.

 109   @retval EFI_SUCCESS           The SCSI Request Packet was sent by the host. For bi-directional
 110                                 commands, InTransferLength bytes were transferred from
 111                                 InDataBuffer. For write and bi-directional commands,
 112                                 OutTransferLength bytes were transferred by
 113                                 OutDataBuffer.
 114   @retval EFI_BAD_BUFFER_SIZE   The SCSI Request Packet was not executed. The number of bytes that
 115                                 could be transferred is returned in InTransferLength. For write
 116                                 and bi-directional commands, OutTransferLength bytes were
 117                                 transferred by OutDataBuffer.
 118   @retval EFI_NOT_READY         The SCSI Request Packet could not be sent because there are too many
 119                                 SCSI Request Packets already queued. The caller may retry again later.
 120   @retval EFI_DEVICE_ERROR      A device error occurred while attempting to send the SCSI Request
 121                                 Packet.
 122   @retval EFI_INVALID_PARAMETER Target, Lun, or the contents of ScsiRequestPacket are invalid.
 123   @retval EFI_UNSUPPORTED       The command described by the SCSI Request Packet is not supported
 124                                 by the host adapter. This includes the case of Bi-directional SCSI
 125                                 commands not supported by the implementation. The SCSI Request
 126                                 Packet was not sent, so no additional status information is available.
 127   @retval EFI_TIMEOUT           A timeout occurred while waiting for the SCSI Request Packet to execute.
