Subject: [dpdk-dev] AF_XDP PMD cannot use with software NICs
Date: Sat, 25 May 2019 09:45:37 +0900	[thread overview]
Message-ID: <678FFC0B-20D6-4913-AF2B-CB08A10F5A7E@gmail.com> (raw)

Hello,

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?

Thanks,
Yutaro
