It recomposes the packet from multiple fragments.

We have received a first fragmented packet.
We start the deframentation by saving the first fragment.

We received a fragmented packet (not first and not last).
We simply save it into our internal list.

We have received a last fragment of the fragmented packets (indicated by the no more fragment field).
We re-construct the packet from the fragments we saved and return the full packet.
