/** @file
This file defines the EFI IPv4 (Internet Protocol version 4)
Protocol interface. It is split into the following three main
sections:
- EFI IPv4 Service Binding Protocol
- EFI IPv4 Variable
- EFI IPv4 Protocol The EFI IPv4 Protocol provides basic
network IPv4 packet I/O services, which includes support for
a subset of the Internet Control Message Protocol (ICMP) and
may include support for the Internet Group Management
Protocol (IGMP).
