After testing, found that: when send a packet which length is 1513 bytes. for i40e nic; the statistic from "show port stats 0" is: RX-bytes: 1513, but before that it show "RX-bytes: 1517". b).DPDK can receive max packet length is mtu + 14(IP_hearder_len) + 4(CRC) + 4(VLAN header len) + 4(VLAN header len).
