Detailed Description

Multicast listener discovery for IPv6. Aims to be compliant with RFC 2710. No support for MLDv2.

Function Documentation

mld6_input()

void mld6_input	(	struct pbuf *	p,
		struct netif *	inp
	)

Process an input MLD message. Called by icmp6_input.

Parameters

p	the mld packet, p->payload pointing to the icmpv6 header
inp	the netif on which this packet was received

mld6_lookfor_group()

struct mld_group* mld6_lookfor_group	(	struct netif *	ifp,
		const ip6_addr_t *	addr
	)

Search for a group that is joined on a netif

Parameters

ifp	the network interface for which to look
addr	the group ipv6 address to search for

Returns

a struct mld_group* if the group has been found, NULL if the group wasn't found.

mld6_report_groups()

void mld6_report_groups

(

struct netif *

netif

)

Report MLD memberships for this interface

Parameters

netif

network interface on which report MLD memberships

mld6_stop()

err_t mld6_stop

(

struct netif *

netif

)

Stop MLD processing on interface

Parameters

netif

network interface on which stop MLD processing

mld6_tmr()

void mld6_tmr

(

void

)

Periodic timer for mld processing. Must be called every MLD6_TMR_INTERVAL milliseconds (100).

When a delaying member expires, a membership report is sent.
