Some services like WSP can send larger messages than the current 'Max Ioctl' limit, this results in the server producing a BUFFER_OVERFLOW status (and additionally clipping the message sent). Add support to allow a client to modify the hardcoded 'Max Ioctl' default value to allow the server to successfully send larger responses.
