ral(4) panic. head, r257837

Hi,

I have following setup:

wlans_ral0="wlan0"
ifconfig_wlan0="WPA"

cloned_interfaces="lagg0 bridge0 tap0"
ifconfig_lagg0="laggproto failover laggport alc0 laggport wlan0 DHCP"
ifconfig_bridge0="addm tap0 addm lagg0"

When system boot I have reproducible panic after messages
Waiting 30s for the default route interface: .
ral0: need multicast update callback
ral0: need multicast update callback
