Accelerating networking with AF_XDP

I wonder (as someone who does not know enough about networking) whether this will be usable in combination of in-device processing (e.g. a card's hardware TCP/IP stack) as well in future. I seem to recall that Linux preferred to do as much of that processing on the CPU as possible until recently, but I don't know whether that is changing or likely to change - I would expect that using specialised network processing hardware has at least the potential to be a performance benefit. I am sure that the answers will enlighten me...
