13 BPF flow dissector is an attempt to reimplement C-based flow dissector logic
20 BPF flow dissector programs operate on an ``__sk_buff``. However, only the
22 ``flow_keys`` is ``struct bpf_flow_keys`` and contains flow dissector input
31 Flow dissector BPF program should fill out the rest of the ``struct
42 dissector looks like::

58 In case of VLAN, flow dissector can be called with the two different states.
67 +-- flow dissector starts here
