Also please check if you get any error messages from the driver when it starts up. > But if I remove the -z, it works, at 2mpps This is the SKB mode. > I believe I am running just i40e without the virtual function driver. > (installed i40e from source with modprobe) Same sources as the kernel you are running? Just checking. Do you have ndo_bpf and ndo_xsk_async_xmit as the latter one was called in 5.3 in your driver? The error message you get is usually because your driver does not support zero-copy mode. > I am running a 5.3 kernel, IS THIS TOO NEW? (details below) No, the newer the better.
