    NPC extraction profile marks layer types
    NPC_LT_LB_CTAG for CTAG and NPC_LT_LB_STAG_QINQ for
    STAG after parsing input packet. Those layer types
    can be used to install ntuple filters using
    vlan-etype option. Below are the commands and
    corresponding behavior with this patch in place.
    
    > alias nt "ethtool -U eth0 flow-type ether"
    
    > nt vlan 5 m 0xf000 action 0
    Input packets with outer VLAN id as 5 i.e,
    stag packets with VLAN id 5 and ctag packets with
    VLAN id as 5 are hit.
    
    > nt vlan-etype 0x8100 action 0
    All input ctag packets with any VLAN id are hit.
    
    > nt vlan-etype 0x88A8 action 0
    All input stag packets with any VLAN id are hit.
    
    > nt vlan-etype 0x8100 vlan 5 m 0xf000 action 0
    All input ctag packets with VLAN id 5 are hit.
    
    > nt vlan-etype 0x88A8 vlan 5 m 0xf000 action 0
    All input stag packets with VLAN id 5 are hit.
