a).According to dpdk commit e8326d3, fix Rx bytes statistics.
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).

DPDK can receive max packet length: mtu + 14(IP_hearder_len) + 4(CRC) + 4(VLAN header len) + 4(VLAN header len)
For example:
MTU = max_pkg_len - 18
if max_pkg_len is 1518 and MTU is 1500, so DPDK can receive max packet length is 1526.
