Currently, the driver returns VLAN_VID_MASK for vlan mask field, when get flow director rule information for rule doesn't use vlan. It may cause the vlan mask value display as 0xf000 in this case, like below: estuary:/$ ethtool -u eth1 50 RX rings available Total 1 rules Filter: 2 Rule Type: TCP over IPv4 Src IP addr: 0.0.0.0 mask: 255.255.255.255 Dest IP addr: 0.0.0.0 mask: 255.255.255.255 TOS: 0x0 mask: 0xff Src port: 0 mask: 0xffff Dest port: 0 mask: 0xffff VLAN EtherType: 0x0 mask: 0xffff VLAN: 0x0 mask: 0xf000 User-defined: 0x1234 mask: 0x0 Action: Direct to queue 3 Fix it by return 0.
