My setup have i40evf driver. I set the dpdk interface's MTU size to 1800. I am sending 100 packets of size 1918 each. I am expecting the drop counter to increment. rte_eth_stats_get() returns i.packets with number of packets I sent. There are no drop counters incrementing. Also my application is not recievi= ng any packets. Is there some issue with dpdk statistics? xstats output is as follows. It is not showing any drops but rx_good_bytes= counts are incrementing. #################################################### NIC extended statistics for port 1 #################################################### rx_good_packets: 656 tx_good_packets: 556 rx_good_bytes: 225160 tx_good_bytes: 33360 rx_errors: 0 tx_errors: 0 rx_mbuf_allocation_errors: 0 rx_q0packets: 0 rx_q0bytes: 0 rx_q0errors: 0 tx_q0packets: 0 tx_q0bytes: 0 rx_bytes: 225160 rx_unicast_packets: 656 rx_multicast_packets: 0 rx_broadcast_packets: 0 rx_dropped_packets: 0 rx_unknown_protocol_packets: 0 tx_bytes: 33360 tx_unicast_packets: 556 tx_multicast_packets: 0 tx_broadcast_packets: 0 tx_dropped_packets: 0 tx_error_packets: 0 Thanks and Regards, Mridula Disclaimer: This communication (including any attachments) is intended for the use of t= he intended recipient(s) only and may contain information that is considere= d confidential, proprietary, sensitive and/or otherwise legally protected. = Any unauthorized use or dissemination of this communication is strictly pro= hibited.
