As described in the bug, when a HA router transitions from "master" to "backup", "keepalived" processes will set the virtual IP in all other HA routers. Each HA router will then advert it and "keepalived" will decide, according to a trivial algorithm (higher interface IP), which one should be "master". At this point, the other "keepalived" processes running in the other servers, will remove the HA router virtual IP assigned an instant before To avoid transitioning some routers form "backup" to "master" and then to "backup" in a very short period, this patch delays the "backup" to "master" transition, waiting for a possible new "backup" state. If during the waiting period (set to the HA VRRP advert time, 2 seconds default) to set the HA state to "master", the L3 agent receives a new "backup" HA state, the L3 agent does nothing.
