conn.log history has letter 'Q'?

so for the history

I inconsistent packet (e.g. SYN+RST bits both set)

I don’t actually know what ‘I’ stands for, but it’s for fin/rst packets, not syn/rst (although that would also be viable as long as fin is also set)

L a fin/rst

I don’t believe that ‘L' is a valid flag for the history field. Where did you find this?
