Detailed Description

Multicast listener discovery for IPv6.

Aims to be compliant with RFC 2710. No support for MLDv2.

Definition in file mld6.h.

Function Documentation

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

Process an input MLD message.

Called by icmp6_input.

Parameters:
pthe mld packet, p->payload pointing to the icmpv6 header
inpthe netif on which this packet was received

Definition at line 222 of file lwip_mld6.c.

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

Search for a group that is joined on a netif.

Parameters:
ifpthe network interface for which to look
addrthe group ipv6 address to search for
Returns:
a struct mld_group* if the group has been found, NULL if the group wasn't found.

Definition at line 139 of file lwip_mld6.c.

void mld6_report_groups ( struct netif *  netif )

Report MLD memberships for this interface.

Parameters:
netifnetwork interface on which report MLD memberships

Definition at line 120 of file lwip_mld6.c.

err_t mld6_stop ( struct netif *  netif )

Stop MLD processing on interface.

Parameters:
netifnetwork interface on which stop MLD processing

Definition at line 91 of file lwip_mld6.c.

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.

Definition at line 457 of file lwip_mld6.c.
