ip6_null_entry will stay a dst based return for lookups that fail to match an entry. Add a new fib6_null_entry which constitutes the root node and leafs for fibs. Replace existing references to ip6_null_entry with the new fib6_null_entry when dealing with FIBs. Signed-off-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
