Problem is distribution : outer-ip is not varied, and udp port is all 2152. I think instead of 5-tuple, src_ip/dst_ip/IP_IDENTIFICATION would do the job. because ip_identification is well distributed, and is same for all fragmented ip packet. Is it possible wth dpdk and x710 or x722 or any other nic?
