@ -776,10 +776,11 @@ peer_notif_delay
Specify the delay, in milliseconds, between each peer
notification (gratuitous ARP and unsolicited IPv6 Neighbor
Advertisement) when they are issued after a failover event.
This delay should be a multiple of the link monitor interval
(arp_interval or miimon, whichever is active). The default
value is 0 which means to match the value of the link monitor
interval.
This delay should be a multiple of the MII link monitor interval
(miimon).
The valid range is 0 - 300000. The default value is 0, which means
to match the value of the MII link monitor interval.
prio
Slave priority. A higher number means higher priority.
