After some debug, we found that pod sends ' IPIP Over GRE ' packet. And DPDK fetch pkt_type from packet descriptor, and it's always zero for this type of packet without IPV4 flag set. The packet descriptor is generated by XXV710 NIC. Our application relies on pkt_type to see if packet's type is IPV4 or not. So we turn to parse ether type ourselves. Best regards
