Squashed commit of the following: net/mld: The MLD logic now compiles and is much less toxic. It still is not a proper MLD implementation: (1) It is basically a port of IGMP, tweaked to work with IPv6 and ICMPv6 MLD messages, (2) it needs a proper analysis and comparison with RFC 3810, and (3) it is completely untested. For this reason, it will remain EXPERIMENTAL for some time. net/mld: Add some missing macros, more fixes related to IPv6 vs IPv4 types, net/mld: More compilation cleaning. Most fixups for IPv6 vs IPv4 types. net/mld: Hook crudely converted .c files into build system and resolve a few of the many, many compilation/design problems. net/mld: Add support for MLD statistics. net/mld: Hook in MLD poll and packet transmission logic. net/mld: Change references to IPv4 definitions to IPv6 definitions; Remove mld_input() since MLD piggybacks on ICMPv6 input. Add functions to catch MLD messages dispatched by ICMPv6 input logic. net/mld: As a starting point, copy all net/igmp/*.c files to net/mld/. and change all occurrences of igmp (or IGMP) to mld (or MLD). net/mld: More compilation cleaning. Most fixups for IPv6 vs IPv4 types. net/mld: Hook crudely converted .c files into build system and resolve a few of the many, many compilation/design problems. net/mld: Add support for MLD statistics. net/mld: Hook in MLD poll and packet transmission logic. net/mld: Change references to IPv4 definitions to IPv6 definitions; Remove mld_input() since MLD piggybacks on ICMPv6 input.
