  Trusted Non-Data command defined in ATA8-ACS.\r

/**\r
  Send a security protocol command to a device.\r
\r
  The SendData function sends a security protocol command containing the payload\r
  PayloadBuffer to the given MediaId. The security protocol command sent is\r
  defined by SecurityProtocolId and contains the security protocol specific data\r
  SecurityProtocolSpecificData. If the underlying protocol command requires a\r
  specific padding for the command payload, the SendData function shall add padding\r
  bytes to the command payload to satisfy the padding requirements.\r
\r
  For devices supporting the SCSI command set, the security protocol command is sent\r
  using the SECURITY PROTOCOL OUT 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 SEND commands defined in ATA8-ACS if PayloadBufferSize\r
  is non-zero. If the PayloadBufferSize is zero, the security protocol command is\r
  sent using the Trusted Non-Data command defined in ATA8-ACS.\r
\r
  If PayloadBuffer is NULL and PayloadBufferSize is non-zero, the function shall\r
  return EFI_INVALID_PARAMETER.\r
\r
  If the given MediaId does not support security protocol commands, the function\r
  shall return EFI_UNSUPPORTED. If there is no media in the device, the function\r
  returns EFI_NO_MEDIA. If the MediaId is not the ID for the current media in the\r
  device, 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
\r
  If the security protocol command completes without an error, the function shall return\r
  EFI_SUCCESS. If the security protocol command completes with an error, the function\r
  shall return EFI_DEVICE_ERROR.\r

                                       means that this function will wait indefinitely for the\r
                                       security protocol command to execute. If Timeout is greater\r
