2 | EFI TCPv6(Transmission Control Protocol version 6) Protocol Definition\r | |
3 | The EFI TCPv6 Service Binding Protocol is used to locate EFI TCPv6 Protocol drivers to create\r | |
4 | and destroy child of the driver to communicate with other host using TCP protocol.\r | |
5 | The EFI TCPv6 Protocol provides services to send and receive data stream.\r | |
