The WebGear cards can be programmed with 16 multicast addresses, from these the NIC itself generates hashes. So what should I do when there are more than 16 mutli-cast addresses? Some drivers appear to set ALLMULTI, others set a promiscuous mode. Some of the promiscuous mode drivers do some filtering before sending packets to BPF/ether_input and other don't. What should I do when I see ALLMULTI? Help!
