The vdev stats in 10.4 firmware is split into two parts (vdev_stats, vdev_stats_extended). The actual stats are captured only in extended vdev stats. In order to enable vdev stats, appropriate feature bit will be set on extended resource config. As FTM related counters are available only on newer 10.4 based firmware, these counters will be displayed only on valid data.
