Before falling back to cellular we used to first delete all the network routing tables and rules for WiFi. This isn't necessary and can take significant time as it requires a lot of netd shelling out to ip and ip[6]tables to flush routes and remove the incoming packet mark rule. Instead have netd delete all the network routing tables and rules after we've either fallen back to cellular or at least kicked off a cellular connection attempt.
