This file defines the EFI IPv4 (Internet Protocol version 4)\r
Protocol interface. It is split into the following three main\r
sections:\r
- EFI IPv4 Service Binding Protocol\r
- - EFI IPv4 Variable\r
- - EFI IPv4 Protocol The EFI IPv4 Protocol provides basic\r
- network IPv4 packet I/O services, which includes support for\r
- a subset of the Internet Control Message Protocol (ICMP) and\r
- may include support for the Internet Group Management\r
- Protocol (IGMP).\r
+ - EFI IPv4 Variable (deprecated in UEFI 2.4B)\r
+ - EFI IPv4 Protocol.\r
+ The EFI IPv4 Protocol provides basic network IPv4 packet I/O services,\r
+ which includes support foR a subset of the Internet Control Message \r
