+
+ Routine Description:
+ Sends a SCSI Request Packet to the SCSI Controller for execution.
+
+ Arguments:
+ This - Protocol instance pointer.
+ Packet - The SCSI request packet to send to the SCSI
+ Controller specified by the device handle.
+ Event - If the SCSI bus where the SCSI device is attached
+ does not support non-blocking I/O, 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_SUCCESS - The SCSI Request Packet was sent by the host
+ successfully, 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 Command 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 - The contents of CommandPacket 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 SCSI initiator(i.e., SCSI
+ Host Controller). 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.
