> Currently the TCP/IP buffer sizes (sendBufferSize/receiveBufferSize) are attributes of AmpqPort.  For the new memory model, supporting different ports using different receive buffers would be problematic and cause inefficient use of direct memory.  Similarly clients using framesizes where the framesize !=buffer size will be inefficient.
> # Remove sendBufferSize/receiveBufferSize from the Port.
> # Make max frame size and sendBufferSize/receiveBufferSize share a single source which should be a context variable belonging to the Broker. Minimum size must be no smaller than SSL netbuffer size
> # The context variable should be evaluated only once at Broker startup.
> # Upgraders should remove the attribute from AmqpPorts
