+        determine whether they have sent or received traffic recently (the
+        precise criteria depends upon the bonding mode, and the state of the
+        slave). Regular traffic is generated via ARP probes issued for the
+        addresses specified by the arp_ip_target option.
+
+        The default value is 0.

+        Example:
