[dpdk-dev] AF_XDP PMD cannot use with software NICs

In current AF_XDP PMD implementation, we cannot use it with software NICs like VETH. 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 useful for testing perpose or using DPDK from containers.

Any thought or future plan for this problem?
