Ethereal-dev: [Ethereal-dev] Re: TCP header lenght highligthed incorrectely in "packet bytes"
That is not really a bug but a sideeffect of how the hex-pane works.
The hex-pane and the API used to specify where fields lie can only
describe full whole bytes.
This means that when there is a small field that only covers a few
bits of a byte, the entire byte will still be highlighted in the hex
pane.
