Network managers like netifd (used in OpenWRT for instance) try to configure interface options after creation but before setting the interface up. Unfortunately the sysfs / bridge currently only allows to configure the hash_max and multicast_router options when the bridge interface is up. But since br_multicast_init() doesn't start any timers and only sets default values and initializes timers it should be save to reconfigure the default values after that, before things actually get active after the bridge is set up. With this patch hash_max and multicast_router attributes can be changed even if the according bridge (port) is down, just like other other bridge (port) attributes allow too.
