A Dprog_flow_dissector.rst10 Flow dissector is a routine that parses metadata out of the packets. It's
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::
49 +-- flow dissector starts here
67 +-- flow dissector starts here
86 +-- flow dissector starts here
95 and BPF flow dissector is not required to handle it.
