+ Send a security protocol command to a device that receives data and/or the result

+
+ If the PayloadBufferSize is zero, the security protocol command is sent using the

+/**
+ Trust transfer data from/to ATA device.
+
+ This function performs one ATA pass through transaction to do a trust transfer from/to
+ ATA device. It chooses the appropriate ATA command and protocol to invoke PassThru
+ interface of ATA pass through.
+
+ @param AtaDevice The ATA child device involved for the operation.
+ @param Buffer The pointer to the current transaction buffer.
+ @param SecurityProtocolId The value of the "Security Protocol" parameter of
+ the security protocol command to be sent.
+ @param SecurityProtocolSpecificData The value of the "Security Protocol Specific" parameter
+ of the security protocol command to be sent.
+ @param TransferLength The block number or sector count of the transfer.
+ @param IsTrustSend Indicates whether it is a trust send operation or not.
+ @param Timeout The timeout, in 100ns units, to use for the execution
+ of the security protocol command. A Timeout value of 0
+ means that this function will wait indefinitely for the
+ security protocol command to execute. If Timeout is greater
+ than zero, then this function will return EFI_TIMEOUT
+ if the time required to execute the receive data command
+ is greater than Timeout.
+
+ @retval EFI_SUCCESS The data transfer is complete successfully.
+ @return others Some error occurs when transferring data.
