C flow dissector supports input flags that tell it to customize parsing by either stopping early or trying to parse as deep as possible. Pass those flags to the BPF flow dissector so it can make the same decisions. In the next commits I'll add support for those flags to our reference bpf_flow.c v3: * Export copy of flow dissector flags instead of moving (Alexei Starovoitov)
