AFAICS that's one *ethernet* frame containing two AMQP methods composed
of four *AMQP* frames. (The deliver method consists of three AMQP frames).
We make no attempt to make AMQP frame boundaries match underlying IP
packets / ethernet frames - it's transparent to clients, and it would be
less efficient for small messages and impossible for large ones.
