  Send a security protocol command to a device that receives data and/or the result\r
  of one or more commands sent by SendData.\r
\r
  The ReceiveData function sends a security protocol command to the given MediaId.\r
  The security protocol command sent is defined by SecurityProtocolId and contains\r
  the security protocol specific data SecurityProtocolSpecificData. The function\r
  returns the data from the security protocol command in PayloadBuffer.\r
\r
  For devices supporting the SCSI command set, the security protocol command is sent\r
  using the SECURITY PROTOCOL IN command defined in SPC-4.\r
\r
  For devices supporting the ATA command set, the security protocol command is sent\r
  using one of the TRUSTED RECEIVE commands defined in ATA8-ACS if PayloadBufferSize\r
  is non-zero.\r
\r
  If the PayloadBufferSize is zero, the security protocol command is sent using the\r
  Trusted Non-Data command defined in ATA8-ACS.\r
\r
  If PayloadBufferSize is too small to store the available data from the security\r
  protocol command, the function shall copy PayloadBufferSize bytes into the\r
  PayloadBuffer and return EFI_WARN_BUFFER_TOO_SMALL.\r
\r
  If PayloadBuffer or PayloadTransferSize is NULL and PayloadBufferSize is non-zero,\r
  the function shall return EFI_INVALID_PARAMETER.\r
\r
  If the given MediaId does not support security protocol commands, the function shall\r
  return EFI_UNSUPPORTED. If there is no media in the device, the function returns\r
  EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the device,\r
  the function returns EFI_MEDIA_CHANGED.\r
\r
  If the security protocol fails to complete within the Timeout period, the function\r
  shall return EFI_TIMEOUT.\r

  If the security protocol command completes without an error, the function shall\r
  return EFI_SUCCESS. If the security protocol command completes with an error, the\r
