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?
