Thank you for your answer. When you say "they are not enabled on the ntuple interface", do you mean the driver is not ready ? The firmware ? Do you know other chipset that do support filters on ethertype ?
Beside the ntuple interface, is there another way to filter packets directly on hardware (and that would allow to filter icmp, or construct complex filtering like "accept dst-port X and dst-port Y, filter other tcp traffic" ?
