Linux kernel 3.0 uses TP_STATUS_VLAN_VALID flag in packet
    auxilliary data (aux->tp_status) to indicate a packet tagged
    with a valid vlan ID 0 with another packet that is not
    vlan tagged. Use this flag to check for the presence of
    a vlan tagged packet. Also be careful not to cause any
    breakage when libpcap is compiled against a newer kernel
    (>=3.0) and used on top of an older kernel that does not
    use this flag.
