There is a time-lag of IFF_RUNNING flag consistency between vlan and real devices when the real devices are in problem such as link or cable broken. This leads to a degradation of Availability such as a delay of failover in HA systems using vlan since the detection of the problem at real device is delayed. We can avoid the linkwatch delay (~1 sec) for devices linked to another ones, since delay is already done for the realdev.
