Hi Sir,

I am trying to send an igmp query from the router to hosts in a subnet. After 
bundling up the igmp packet into an ip packet, then invoking 

IPOutgoingPacket(out_pkt, dst_ip, igmpPacketLength, 1, IGMP_PROTOCOL); 
//{please note that dst_ip is, and IGMP_PROTOCOL = 2}

then opening up wireshark, I note that the router uses the arp protocol to send 
a broadcast asking for the mac address of a host with IP address! I'd 
like the router to broadcast the packet in the subnet, and let the interested 
hosts pick up the packet.
