+ Send a security protocol command to a device that receives data and/or the result
+ of one or more commands sent by SendData.
+
+ The ReceiveData function sends a security protocol command to the given MediaId.
+ The security protocol command sent is defined by SecurityProtocolId and contains
+ the security protocol specific data SecurityProtocolSpecificData. The function
+ returns the data from the security protocol command in PayloadBuffer.
+
+ For devices supporting the SCSI command set, the security protocol command is sent
+ using the SECURITY PROTOCOL IN command defined in SPC-4.
+
+ For devices supporting the ATA command set, the security protocol command is sent
+ using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize
+ is non-zero.
+
+ If the PayloadBufferSize is zero, the security protocol command is sent using the
+ Trusted Non-Data command defined in ATA8-ACS.
+
+ If PayloadBufferSize is too small to store the available data from the security
+ protocol command, the function shall copy PayloadBufferSize bytes into the
+ PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.
+
+ If PayloadBuffer or PayloadTransferSize 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. The caller is responsible for having
+ either implicit or explicit ownership of the buffer.
+ @param PayloadTransferSize A pointer to a buffer to store the size in bytes of the
+ data written to the payload data buffer.
+
+ @retval EFI_SUCCESS The security protocol command completed successfully.
+ @retval EFI_WARN_BUFFER_TOO_SMALL The PayloadBufferSize was too small to store the available
+ data from the device. The PayloadBuffer contains the truncated data.
+ @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 or PayloadTransferSize is NULL and
+ PayloadBufferSize is non-zero.

+ protocol command to execute.

+ Send a security protocol command to a device.
+
+ The SendData function sends a security protocol command containing the payload
+ PayloadBuffer to the given MediaId. The security protocol command sent is

+ SecurityProtocolSpecificData. If the underlying protocol command requires a
