Gregory Nutt	62e4a41209	net/mld: Add reference counting on the group joins. If there are multiple joins from the same group on this, the don't really leave the group until the matching number of leaves happen. Also add to hooks for the router case: Keep track of the number members NOT on this host. Integrate this with the Leave logic to that the group structure can persist while there no non-local members of the group as well.	2018-11-06 14:46:03 -06:00
Gregory Nutt	3db3c3952b	net/mld: Standard usage of debug output macros. Add configuration options to enable MLD debug even when there network debug is disabled. Add configuration option to dump the content of outgoing MLD packets.	2018-11-05 18:39:55 -06:00
Gregory Nutt	6c0ab0e077	Squashed commit of the following: ... include/nuttx/net/ipv6ext.h: Fix some terminology: Hop-by-hop, not Hop-to-hop or Hop2hop. net/devif/ipv6_input.c and net/icmpv6/icmpv6_input.c: Add logic to skiip over the variable number of IPv6 extension headers that may be present between the IPv6 header and the transport layer header. The extension headers are simply ignored. This is necessary because with MLD, certain incoming messages may have, at a mimimum, a Router Alert Hop-by-hop extension header. net/inet/ipv6_setsockopt.c: Implement the IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP socket options.	2018-11-02 12:06:57 -06:00
Gregory Nutt	6d93658ff8	Add new configuratin CONFIG_NET_MCASTGROUP. This option is selected automatically if either CONFIG_NET_IGMP or CONFIG_NET_MLD are selected. Most conditional logic based on CONFIG_NET_IGMP replaced with conditioning on CONFIG_NET_MCASTGROUP.	2018-10-31 15:03:51 -06:00
Gregory Nutt	dde1e89b8c	net/mld: Add basic build structure for Multicast Listener Discovery (MLD). No real MLD logic yet. Only a few hooks to capture and dispatch MLD ICMPv6 packets.	2018-10-31 14:10:19 -06:00
