alt Hacker NewsI think, and I'm saying this in part to get someone to correct me, that post-XDP (so 5 years or so now) DPDK is basically obsolete. Is there a circumstance where it would make sense to start from DPDK rather than XDP?

I think you're correct. Not really aware of any real limitations, other than it's slightly slower than dpdk (it's not a complete bypass), but at a much easier ease of use.

At this point there's a much bigger ecosystem for DPDK than AF_XDP I think. Also more people know about DPDK than AF_XDP right now e.g. the Ostinato traffic generator's line-rate Turbo functionality uses AF_XDP but most customers assume it uses DPDK.
