Hi, we are developing system heavy using eBPF programs and AF_XDP and noticed something that looks like regression.
In my setup I have system with 2 NICs: XXV710 and X722, kernel 5.2.1. Driver version 2.8.20-k (packed into kernel): XXV710 - works fine with AF_XDP in zero copy mode; X722 - crash on loading eBPF program (seems to be known bug AFAIK). Driver version 2.9.21 (latest available from intel.com): XXV710 - "operation not supported" error when initializing AF_XDP socket in zero copy mode; X722 - the same, "operation not supported" error when initializing AF_XDP socket in zero copy mode. And my final goal is to run X722 in AF_XDP zero copy which seems hard to achieve now. Any points, ideas, thing to check or debug? - any help is very valuable.
