+ 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 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.

+ is non-zero. If the PayloadBufferSize is zero, the security protocol command is
