Hi: I am trying to get an XDP program working with an mlx5 based nic and not having much success. The same program works fine with sfc and i40e, but with mlx5 it seems to be limited. I added a trace_printk and basically it seems to only run cpu 1 and rx queue 0. Fiddling with the number of channels (ethtool -L) I was, for a brief moment, seeing the program running on different cpu with a different rx-queue id. I am clearly missing some setting that is needed for mlx5, but I have not been able to find any wiki, conference paper or git commit message with helpful hints. Do you have any references you can forward? Server has 48 cores, 96 threads and RPS is configureed. The card is: d8:00.0 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx] Thanks, David
