I've tried also with intel NIC (e100 driver) result is the same. Unicast MAC address was added to multicast cache, but I cannot ping system from remote machine with static MAC entry. On tcpdump output I can see arriving frames with correct address (the unicast one I addes to multicast filter), but for some reason system is not responding. Can you provide Jeff or anybody else a name of NIC that is capable to support multiple unicast MAC addresses? One more question is it possible to deactivate MAC filter on NIC so that I will receive everything (no matter if this will be efficient or not) and pass it to L3 routines? I tried to set NIC into promisc mode: "ip l set dev eth0 promisc on" but it looks like even with having promisc mode enabled system is not responding.
