Remove track6-interface and track6-prefix-id from interfaces->lan in default config.xml
1. <track6-interface>wan</track6-interface> and <track6-prefix-id>0</track6-prefix-id> of interfaces->lan from /conf.default/config.xml will get copied over to /cf/conf/config.xml
2. Without going to the LAN interface configuration page to click "Save" at least once, those 2 entries will stay there (even after going through the first run wizard).
3. In the services_radvd_configure function in /etc/inc/services.inc, the existence of those 2 entries will cause /var/etc/radvd.conf to be written with "AdvSendAdvert on;" for the LAN interface
4. Hence, IPv6 router advertisements will be periodically sent even if IPv6 is never enabled for the network.
