2 | This file defines the EFI IPv6 (Internet Protocol version 6)\r | |
3 | Protocol interface. It is split into the following three main\r | |
4 | sections:\r | |
5 | - EFI IPv6 Service Binding Protocol\r | |
6 | - EFI IPv6 Variable (deprecated in UEFI 2.4B)\r | |
7 | - EFI IPv6 Protocol\r | |
8 | The EFI IPv6 Protocol provides basic network IPv6 packet I/O services,\r | |
9 | which includes support for Neighbor Discovery Protocol (ND), Multicast\r | |
10 | Listener Discovery Protocol (MLD), and a subset of the Internet Control\r | |
11 | Message Protocol (ICMPv6).\r | |
