+        When an arp_ip_target is configured the bonding driver will
+        attempt to automatically determine what vlans the arp probe will
+        pass through. This process of gathering vlan tags is required
+        for the arp probe to be sent. However, in some configurations

+        supply a list of vlan tags. To specify a list of vlan tags
+        append the ipv4 address with [tag1/tag2...]. For example:
+        arp_ip_target=10.0.0.1[10]. If you simply need to disable the
+        vlan discovery process you may provide an empty list, for example:
