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