I don't think this is an appropriate feature for dnsmasq, the philosophy
is that it should provide a basic RA service for networks which are
really using DHCPv6 for the complex stuff. For complex RA setups, radvd
is the way to go, I don't want to re-implement all of radvd.

If you configure DHCPv6 for a subnet, you get stateful DHCPv6 but no RA.
That should combine with radvd fine, I think.
