Comment 5 for bug 252945

You could also include the attached diff. I'm pretty sure it will record the same bytes multiple times as various layers process them, but at least it will dump the info about what *we* think we are transmitting and receiving, and we can probably filter it after the fact to avoid the duplication.

(I'm hoping it will be obvious when we see 2 classes always follow eachother with the same number of bytes processed.)
