    flow_dissector: Get vlan priority in addition to vlan id · f6a66927
    Hadar Hen Zion 提交于
    Add vlan priority check to the flow dissector by adding new flow
    dissector struct, flow_dissector_key_vlan which includes vlan tag
    fields.
    
    vlan_id and flow_label fields were under the same struct
    (flow_dissector_key_tags). It was a convenient setting since struct
    flow_dissector_key_tags is used by struct flow_keys and by setting
    vlan_id and flow_label under the same struct, we get precisely 24 or 48
    bytes in flow_keys from flow_dissector_key_basic.
    
    Now, when adding vlan priority support, the code will be cleaner if
    flow_label and vlan tag won't be under the same struct anymore.
