If you actually wanted to filter only UDP/IPv4 packets for VID 0-31 then the correct syntax would be: ethtool -U eth5 flow-type udp4 vlan 0 vlan-mask 0xf01f If you don't care about the layer 3/4 protocols then you would need to use 'flow-type ether', but no driver implements that yet. (Well, sfc implements the *type*, but not filtering by VID only.) Ben. -- Ben Hutchings, Senior Software Engineer, Solarflare Not speaking for my employer; that's the marketing department's job.
