           Summary: About i40e statistics: When all packets overruns,
                    rx_packets is 0, but rx_bytes still increasing
           Product: DPDK
           Version: 20.08
          Hardware: ARM
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal

Target Milestone: ---

Driver: i40e, 8086:1572
I run dpdk program with i40e nic. When all packet overruns, the “rx_packets” stop increasing, and I found “rx_bytes” is still increasing, which i think, is expected to stop increasing. The statistics comes from the function "rte_eth_stats_get()"
Could you please help me to find the reason?
