This ensures igmp_init is called, which sets up the RX filter for the allsystems group and adds it to the list of groups so it should be found by igmp_lookfor_group. |

There are 0 votes so far. Votes easily highlight which items people would like to see resolved in priority, independently of the priority of the item set by tracker managers.

You can call igmp_start() manually for that netif if you don't want to change TI's sources, but setting the flag is definitively preferred.
