Why would I want to run AF_XDP without ZC? The main reason for having AF_XDP support in drivers is the zero copy, right?
In general I agree with you on this point. Short-term, I see copy-mode useful for API adoption reasons (as XDP_SKB), so from that perspecitve it's important. Longer term I'd like to explore AF_XDP as a faster AF_PACKET for pcap functionality. Björn
