Whenever a flow is hw offloaded it is required to query the hw for the flow counters statistics, specifically the number of packets and the number of bytes used by the flow. In order to successfully call DPDK rte_flow_query() API, a 'count' action must be implicitly added to the flow actions when calling DPDK rte_flow_create() API.
