Description

Current, proton-j (and c) will send the largest frames it can as permitted by a peers max-frame size. Where peers don't set a max frame size, or use a very large one, then this typically results in a single outgoing frame being emitted, which for large messages can be inefficient and also requires more memory than might be desirable. There is currently no way to govern the maximum size of the outgoing frames (besides the peers advertised max frame size), such a mechanism should be added.
