I config the ENET Address filtering mode to 100 (Promiscuous filtering), and connect STR912 to hub with PC. Then I send out a IPv6 Neighbor-Discovery packet (Dest MAC address : 33:33:ff:84:e1:fe), but I cannot receive it on STR912 board. I don't know how to config STR912 and let it can receive this kind of packets. Does anyone know how to do ? Thanks.
