Bundle Add Message and Request Forward Message, which is part of OpenFlow 1.4, encapsulates an OpenFlow message in side an OpenFlow message. This patch prepares for this by adding a MsgInMsgBase class, a subclass of MsgBase which allows its subclasses to include subclasses of either MsgInMsgBase or MsgBase when when parsing classes from JSON: The MsgBase class does not allow this. This change has three parts: * Remove the assertion in ofproto_parser.py:StringifyMixin::cls_from_jsondict_key() that cls is not a subclass of MsgBase. * Pass **additional_args to various stringify.py:StringifyMixin decoder methods to make the datapath available when instantiating MsgBase subclasses. * Override _decode_value() in MsgInMsgBase to pass **additional_args to decoder. The method in the parent class, StringifyMixin, does not pass **additional_args. The effect is to pass a datapath argument if the class is a subclass of MsgInMsgBase but not if the class is a direct subclass of MsgBase. By only making messages which allow messages inside them subclasses of MsgInMsgBase this allows the datapath argument to be passed to the decoder if and only if needed.

What's Ryu
Ryu is a component-based software defined networking framework.
Ryu provides software components with well defined API that make it easy for developers to create new network management and control applications. Ryu supports various protocols for managing network devices, such as OpenFlow, Netconf, OF-config, etc. About OpenFlow, Ryu supports fully 1.0, 1.2, 1.3, 1.4 and Nicira Extensions.
All of the code is freely available under the Apache 2.0 license. Ryu is fully written in Python.
Quick Start
Installing Ryu is quite easy:
% pip install ryuIf you prefer to install Ryu from the source code:
% git clone git://github.com/osrg/ryu.git
% cd ryu; python ./setup.py installIf you want to use Ryu with OpenStack, please refer detailed documents. You can create tens of thousands of isolated virtual networks without using VLAN. The Ryu application is included in OpenStack mainline as of Essex release.
If you want to write your Ryu application, have a look at Writing ryu application document. After writing your application, just type:
% ryu-manager yourapp.pySupport
