Throughput increase is observed in l3fwd as now the vpmd can be used with hw_ip_checksum enabled and without needing '--parse-ptype'. The benefits to applications using this functionality is realized when Ethernet processing and L3/L4 checksum validation can be skipped. We hope others can also test performance in their applications while conducting a review of this series.
