+.It Li arp.nd_delay

+.It Li arp.nd_bmaxtries

+The variable defines the number of consecutive hints the neighbor discovery
+layer will take.
+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.
