Yeah unfortunately I don't really know how to _manually_ reproduce. I don't know why I'm getting these status descriptors, but I'm getting them reproducibly every few minutes on ubuntu 24.04 across 3 machines where I've hit this bug/tested the fix. The machines are doing ~300Mbps of UDP traffic, some of which is done using AF_XDP. The AF_XDP code is TX only, so it's executing the build-skb-in-zc-path all the time as all the ingress traffic goes to sockets. If you have any idea on how to reliably produce the descriptors I'm happy to give it a try.
