Hi

Working on an update of the QUIC ECN draft.
Stumbled on the sent_bytes metric (which will be complemented with ECN marked bytes et.c )

Which layers does the sent_bytes metric include ?
I would assume that the IP layer is included ? and that would of course be useful for instance if ConEx ever happens (RFC6789).
On the other hand I wonder how straightforward it is to get the IP header size form the application layer, it may be easy, and it may be tricky.
In any case this needs clarification.
