The coarse-grained timing is only used when the system time changes or an unlikely length of time has passed since the sending of the AoE command. Users will not be impacted unless their system clock is very inaccurate or something unusual (e.g., 10 GbE link reset) happens during the period when the aoe driver is handling the failure of a port on the AoE target. Being effected will mean that an AoE target could be considered "down" too eagerly.
