Redirect NIC to TAP doesn't work when XDP is attached in driver mode. It works when they are both in generic mode. I haven't tried other combinations of attachment modes (one driver, other generic etc.).It should work. I tested with i40e/ixgbe/mlx4 in the past. What eBPF program did you use? (Is it the one in samples/bpf?) I would test it by myself. (It's near to spring festival, so I can only check after the holiday).As Maciej Fijalkowski pointed out: "Looks like Netronome driver still doesn't support XDP_REDIRECT in native mode." So, that is likely the problem.
I see. Thanks
