| bdb140d7 | 2 | EFI TCPv4(Transmission Control Protocol version 4) Protocol Definition\r |
| d1f95000 | 3 | The EFI TCPv4 Service Binding Protocol is used to locate EFI TCPv4 Protocol drivers to create\r |
| d01c093a | 4 | and destroy child of the driver to communicate with other host using TCP protocol.\r |
| 5 | The EFI TCPv4 Protocol provides services to send and receive data stream.\r | |
