  EFI FTPv4 (File Transfer Protocol version 4) Protocol Definition\r
  The EFI FTPv4 Protocol is used to locate communication devices that are \r
  supported by an EFI FTPv4 Protocol driver and to create and destroy instances\r
  of the EFI FTPv4 Protocol child protocol driver that can use the underlying\r
  communication device.\r
  The definitions in this file are defined in UEFI Specification 2.3, which have\r
  not been verified by one implementation yet.\r

/**\r
  Download a data file "directory" from a FTPv4 server. May be unsupported in some EFI \r
  implementations.\r
\r
  The ReadDirectory() function is used to return a list of files on the FTPv4 server that\r
  logically (or operationally) related to Token.Pathname, and optionally wait for completion.\r
  When the download operation completes, whether successfully or not, the Token.Status field \r
  is updated by the EFI FTPv4 Protocol driver and then Token.Event is signaled (if it is not\r
  NULL). Data will be downloaded from the FTPv4 server into Token.DataBuffer. If the file size\r
  is larger than Token.DataBufferSize, Token.DataCallback will be called to allow for processing\r
  data and then new data will be placed at the beginning of Token.DataBuffer. \r
