| 3 | This file defines the EFI IPv4 (Internet Protocol version 4)\r | |
| 4 | Protocol interface. It is split into the following three main\r | |
| 5 | sections:\r | |
| 6 | - EFI IPv4 Service Binding Protocol\r | |
| 7 | - EFI IPv4 Variable\r | |
| 8 | - EFI IPv4 Protocol The EFI IPv4 Protocol provides basic\r | |
| 9 | network IPv4 packet I/O services, which includes support for\r | |
| 10 | a subset of the Internet Control Message Protocol (ICMP) and\r | |
| 11 | may include support for the Internet Group Management\r | |
| 12 | Protocol (IGMP).\r | |
