[lwip-users] IPv6 porting, need help in netif->mld_mac_filter

[manoj.biswas]

Hi,

 

I am new to LWIP IPv6 implementation.

I am trying to port it for my device, I have set below netif param and #define to respective values

 

#define LWIP_IPV6                             1

#define LWIP_IPV6_DHCP6             1

#define LWIP_ICMP6                          1

#define LWIP_IPV6_AUTOCONFIG              1

#define LWIP_IPV6_NUM_ADDRESSES     6

 

netif->ip6_autoconfig_enabled = 1;

netif->output_ip6 = ethip6_output;

 

With this setting I could see LWIP is sending

a>     “Multicast Listner Report”

b>    Neighbour solicitation

c>     Router Solicitation (to ff02::2)

 

Also I can see my router is sending me Router advertisement (to ff02::1) which I am not able to receive. I feel this is because I haven’t set below parameter in netif

netif->mld_mac_filter = ?????;

 

I am not sure what this function should be, As I know I have to join this multicast group to receive the advertisement packet.

 

Can someone help me in what this function should point to and is some example already  available?

 

Thanks and  Regards,

Manoj
