ipv4/ipv6: Prepare for new route gateway semantics.
In the future the ipv4/ipv6 route gateway will take on two types
of values:
1) INADDR_ANY/IN6ADDR_ANY, for local network routes, and in this case
the neighbour must be obtained using the destination address in
ipv4/ipv6 header as the lookup key.
2) Everything else, the actual nexthop route address.
So if the gateway is not inaddr-any we use it, otherwise we must use
the packet's destination address.
