8691d75917 odhcp6c: add route-workaround for broken IPv6-ISPs
Some ISP seem to only do stateful DHCPv6 and not sending RAs.
This is technically broken because plain DHCPv6 doesn't carry routes.

We work around here by faking a default route to the DHCPv6 server
if we do not receive a useful RA from the ISP.

This workaround can be turned off with: option fakeroutes 0

02c763c4ab odhcp6c: Revert to slightly modified version of old behaviour
Latest changes broke source-restriction of on-link routes. Restoring
old-behaviour but adding correct source-restrictions which prevents
the offlink handler to remove the on-link route.
