As the name suggests you should use

	/proc/sys/net/ipv4/conf/all/arp_accept

The documentation says that if arp_accept is 0, unsolicited arp
replies are dropped. Doesn't that interfere with failover services
such as vrrp, keepalived, ucarp etc? I thought they did unsolicited
arp when failing over.
