All fragments of an ipv4 packet need to go to same receive queue and handled by same lcore for lockless reassembly. Looks like Intel 82599 supports RSS IPv4 hashing using just source and dest address fields and that should put all fragments on same queue ( can be enabled by ETH_RSS_IPV4 in rte_eth_rss_conf->rs_hf). Please let me know whether my understanding is correct. Thanks Shyam
