Beryllium Feature Request for ofextensions/circuitsw project

ofextensions/circuitsw project depends on openflowplugin and needs the following -

Circuit Switches communicate to the controller using the openflow protocol.
In addition to the standard protocol, Circuit Switch has specific data to be sent to the controller. For this, Circuit Switch uses the experimenter and multipart experimenter messages.

We have the support for multipart experimenter messages in the openflowjava.

In the current openflow plugin, we do not have support for the multipart experimenter messages.

1. We must have the multipart experimenter message support in the openflow plugin. Basically the framework should provide the ability to implement a service to send the multipart experimenter messages to the switches.
2. Distinguish and send the experimenter port desc statistics message instead of the standard port desc statistics message.
3. Would like to know where should the code built based on the experimenter framework go into? Should it be part of the openflowplugin/extensions? Or Should it be part of the ofextensions/circuitsw project?
