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