Sorry if I am missing something, but a fdb_entry maps a hardware address to a port number. This arbitary port number points to the port_info structure which seems to only hold information about what bridge it belongs to. And the bridge_info structure doesn't contain any information either. The only place I can find something that might be useful is in linux/netdevice.h and the "struct net_bridge_port *br_port" under the net_device structure. This is inside the kernel as it needs __KERNEL__ defined in order to use it, or is this what I am looking for? Thank you once again Joergen
