/* The Fragmenter is a bit tricky, because there are 5 sizes in play:
* max size -- the maximum transfer size possible
* orig size -- the original pre-fragmenter size
* frag size -- the modified post-fragmenter size
* min size -- the threshold below which frag=orig
* beat size -- the amount transfered on any given beat
*
* The relationships are as follows:
* max >= orig >= frag
* max > min >= beat
* It IS possible that orig <= min (then frag=orig; ie: no fragmentation)
*
* The fragment# (sent via TL.source) is measured in multiples of min size.
* Meanwhile, to track the progress, counters measure in multiples of beat size.
*

/* The Fragmenter is a bit tricky, because there are 5 sizes in play:
* max size -- the maximum transfer size possible
* orig size -- the original pre-fragmenter size
* frag size -- the modified post-fragmenter size
* min size -- the threshold below which frag=orig
* beat size -- the amount transfered on any given beat
*
* The relationships are as follows:
* max >= orig >= frag
* max > min >= beat
* It IS possible that orig <= min (then frag=orig; ie: no fragmentation)
*
* The fragment# (sent via TL.source) is measured in multiples of min size.
* Meanwhile, to track the progress, counters measure in multiples of beat size.
*
* Here is an example of a bus with max=256, min=8, beat=4 and a device supporting 16.
