I agree there is no added value to have two ways to do the same thing. I
guess the discussion here is whether lw46 should use dhcpv4-over-dhcpv6 or
OPTION_S46_IPV4ADDRESS option in map-dhcp. No matter what we decide, we
should only need one. I tend to agree with Ole to take out S46 option from
the map-dhcp and let the map-dhcp draft focus on map.
