+ defined by SecurityProtocolId and contains the security protocol specific data
+ SecurityProtocolSpecificData. If the underlying protocol command requires a
+ specific padding for the command payload, the SendData function shall add padding
+ bytes to the command payload to satisfy the padding requirements.
+
+ For devices supporting the SCSI command set, the security protocol command is sent
+ using the SECURITY PROTOCOL OUT command defined in SPC-4.
+
+ If PayloadBuffer is NULL and PayloadBufferSize is non-zero, the function shall
+ return EFI_INVALID_PARAMETER.
+
+ If the given MediaId does not support security protocol commands, the function
+ shall return EFI_UNSUPPORTED. If there is no media in the device, the function
+ returns EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the
+ device, the function returns EFI_MEDIA_CHANGED.
+
+ If the security protocol fails to complete within the Timeout period, the function
+ shall return EFI_TIMEOUT.
+
+ If the security protocol command completes without an error, the function shall return
+ EFI_SUCCESS. If the security protocol command completes with an error, the function
+ shall return EFI_DEVICE_ERROR.
+
+ @param This Indicates a pointer to the calling context.
+ @param MediaId ID of the medium to receive data from.
+ @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.
+ @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 PayloadBufferSize Size in bytes of the payload data buffer.
+ @param PayloadBuffer A pointer to a destination buffer to store the security
+ protocol command specific payload data for the security
+ protocol command.
+
+ @retval EFI_SUCCESS The security protocol command completed successfully.
+ @retval EFI_UNSUPPORTED The given MediaId does not support security protocol commands.
+ @retval EFI_DEVICE_ERROR The security protocol command completed with an error.
+ @retval EFI_NO_MEDIA There is no media in the device.
+ @retval EFI_MEDIA_CHANGED The MediaId is not for the current media.
+ @retval EFI_INVALID_PARAMETER The PayloadBuffer is NULL and PayloadBufferSize is non-zero.
+ @retval EFI_TIMEOUT A timeout occurred while waiting for the security
+ protocol command to execute.
