bdb140d7 1/** @file\r
bdb140d7 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\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

902 Polls for incoming data packets and processes outgoing data packets.\r
bce46f7e 903\r
bdb140d7 904 The Poll() function polls for incoming data packets and processes outgoing data\r
905 packets. Network drivers and applications can call the EFI_IP6_PROTOCOL.Poll()\r
906 function to increase the rate that data packets are moved between the communications\r
907 device and the transmit and receive queues.\r
bce46f7e 908\r
bdb140d7 909 In some systems the periodic timer event may not poll the underlying communications\r
910 device fast enough to transmit and/or receive all data packets without missing\r
911 incoming packets or dropping outgoing packets. Drivers and applications that are\r
912 experiencing packet loss should try calling the EFI_IP6_PROTOCOL.Poll() function\r
913 more often.\r
