+IPv6 neighbor discovery permits upper layer protocols to supply reachability

+The variable defines the number of consecutive hints the neighbor discovery

+For example, by setting the variable to 3, neighbor discovery layer
+will take 3 consecutive hints in maximum.
+After receiving 3 hints, neighbor discovery layer will perform
+normal neighbor discovery process.
