[Tuexen Michael] What do you mean by send failure? The reasons for
communication lost might be
- excessive retransmissions
- reception of an abort
Then we go through the send/retransmission queue and deliver the
chunks
to the UL. We know whether it was sent or not.

[Tuexen Michael] I think we do it on TSN base, this means on per
fragment
base. You since it is an API question, you can do whatever you want.

[Tuexen Michael] Maybe I'm wrong, but I do not know of people using
this feature.
