+ EFI TCPv4(Transmission Control Protocol version 4) Protocol Definition\r
The EFI TCPv4 Service Binding Protocol is used to locate EFI TCPv4 Protocol drivers to create\r
and destroy child of the driver to communicate with other host using TCP protocol.\r
The EFI TCPv4 Protocol provides services to send and receive data stream.\r
