inwiefern berührt das denn unsere "default" sysctl settings in
https://github.com/FreifunkFranken/firmware/blob/master/src/packages/fff/fff-network/files/etc/sysctl.d/50-fff-network.conf

Passiert der netifd "danach" und sind die settings daher irrelevant, oder gibt es hier einen anderen Mechanismus?
Brauchen wir all die Settings in der sysctl überhaupt, oder macht OpenWrt nicht u.U. einen der IPv6 config dort auch "automatisch"?

Bitte auch gleich die Funktionen selbst mit töten, die stehen in der gleichen Datei ganz oben (auch setAutoConf kann weg).
