Because it allocates umem with RTE_MEMZONE_IOVA_CONTIG. Since AF_XDP itself is usable with any network devices, I think it is better= to have option to take umem with RTE_MEMZONE_SIZE_HINT_ONLY. It is also use= ful for testing perpose or using DPDK from containers. Any thought or future plan for this problem? Thanks, Yutaro=
