+ Specify the number of peer notifications (gratuitous ARPs and
+ unsolicited IPv6 Neighbor Advertisements) to be issued after a
+ failover event. As soon as the link is up on the new slave
+ (possibly immediately) a peer notification is sent on the
+ bonding device and each VLAN sub-device. This is repeated at
+ each link monitor interval (arp_interval or miimon, whichever
+ is active) if the number is greater than 1.
+
+ The valid range is 0 - 255; the default value is 1. These options
+ affect only the active-backup mode. These options were added for
+ bonding versions 3.3.0 and 3.4.0 respectively.
+
+ From Linux 2.6.40 and bonding version 3.7.1, these notifications
+ are generated by the ipv4 and ipv6 code and the numbers of
+ repetitions cannot be set independently.
