FS#713 - netifd: substantially more IFUP events are being created

I can confirm this using tools that use an interface trigger with optional interfaces. If WAN (ip4 only) and not WAN6 is used restarts almost never occur. If WAN6 is included, then restarts are occurring every few minutes.

for iface in $ifacelist
do
    procd_add_interface_trigger "interface.*" "$iface" /etc/init.d/[script] [command]
done
