+/*++
+
+ Routine Description:
+ Sends a SCSI Request Packet to a SCSI device that is attached to
+ the SCSI channel. This function supports both blocking I/O and
+ non-blocking I/O. The blocking I/O functionality is required,
+ and the non-blocking I/O functionality is optional.
+
+ Arguments:
+ This - Protocol instance pointer.
+ Target - The Target ID of the SCSI device to
+ send the SCSI Request Packet.
+ Lun - The LUN of the SCSI device to send the
+ SCSI Request Packet.
+ Packet - A pointer to the SCSI Request Packet to send
+ to the SCSI device specified by Target and Lun.
+ Event - If non-blocking I/O is not supported then Event
+ is ignored, and blocking I/O is performed.
+ If Event is NULL, then blocking I/O is performed.
+ If Event is not NULL and non blocking I/O is
+ supported, then non-blocking I/O is performed,
+ and Event will be signaled when the SCSI Request
+ Packet completes
+
+ Returns:
+ EFI_SUCCESSThe - SCSI Request Packet was sent by the host, and
+ TransferLength bytes were transferred to/from
+ DataBuffer.See HostAdapterStatus, TargetStatus,
+ SenseDataLength,and SenseData in that order
+ for additional status information.
+ EFI_BAD_BUFFER_SIZE - The SCSI Request Packet was executed, but the
+ entire DataBuffer could not be transferred.
+ The actual number of bytes transferred is returned
+ in TransferLength. See HostAdapterStatus,
+ TargetStatus, SenseDataLength, and SenseData in
+ that order for additional status information.
+ EFI_NOT_READY - The SCSI Request Packet could not be sent because
+ there are too many SCSI Request Packets already
+ queued. The caller may retry again later.
+ EFI_DEVICE_ERROR - A device error occurred while attempting to send
+ the SCSI Request Packet. See HostAdapterStatus,
+ TargetStatus, SenseDataLength, and SenseData in
+ that order for additional status information.
+ EFI_INVALID_PARAMETER - Target, Lun, or the contents of ScsiRequestPacket
+ are invalid. The SCSI Request Packet was not sent,
+ so no additional status information is available.
+ EFI_UNSUPPORTED - The command described by the SCSI Request Packet
+ is not supported by the host adapter. The SCSI
+ Request Packet was not sent, so no additional
+ status information is available.
+ EFI_TIMEOUT - A timeout occurred while waiting for the SCSI
+ Request Packet to execute. See HostAdapterStatus,
+ TargetStatus, SenseDataLength, and SenseData in
+ that order for additional status information.
