[net2-wg] tos msg vs ADU send for collection

[Omprakash Gnawali]

This is a follow up on a specific thread from our meeting
yesterday. It was mentioned that providing tos msg send will enable
implementing ADU send on top of it but not necessarily the other way
around.

It is not clear why this is the case. One can call the ADU send with a
tos msg as an argument; the ADU send which will package it inside its
own tos msg. The argument why this does not work is because there are
headers in a tos msg. As far as I can tell, collection applications do
not care about the header in a tos msg. Users of collection should
only care about data.

Are there instances when users of collection care about the header ?
If there are instances of this then collection must provide a tos msg
send interface.
