I've noticed a few minor issues with the new TCP tcp.analysis.bytes_in_flight
information.
1) At the start of a traffic capture, if a TCP transfer was already underway,
the segments at the beginning of the capture show a very low bytes_in_flight
measurement, even if many more bytes were actually in flight
2) If there is a prolonged period of time where frames are missing from the
traffic capture, the bytes_in_flight measurement will show as too high in the
segments immediately following that event.
3) In a general sense, I'm noticing a lot of examples where the
bytes_in_flight measurement is off (too high) by up to a couple segments worth
of data.
I'm attaching a patch containing my fixes for these minor issues. This patch
has been fuzz tested.
