Code Quality & Modernization

• Applied clang modernize across all files
• Reformatted code with uncrustify using INET-specified style
• Fixed header guards with __OPENFLOW_ prefix and added missing ones
• Removed redundant default constructor calls for cleaner C++ code

OpenFlow Protocol & Compliance

• Added comprehensive RFC 1.0 compliance analysis documentation
• Enhanced OpenFlow message descriptors for better qtenv visibility
• Added OpenFlow.msg and improved message structure definitions
• Fixed Open_Flow_Message.msg structure

Controller Applications

• Removed unused @signal from ControllerInvolvementFilter
• Fixed KN_LLDPForwarding to extend LLDPForwarding properly
• Added missing @signal for KN_LLDPForwarding
• Added missing type property for @signal declarations
• Fixed Enter_Method() positioning in KN_LLDPForwarding
• Enhanced controller app dynamic_cast patterns across Kandoo, HyperFlow, and standard apps

Data Structures & Visibility

• Replaced std::list with MSG array in controlChannel for better qtenv visibility
• Enhanced DataChannelEntry MSG descriptor with detailed field definitions
• Improved KandooEntry MSG descriptor for qtenv inspection
• Added Switch_Info to HF_ChangeNotification.msg
• Added getter functions for ControlChannelEntry 'switches' member
• Replaced invisible DataChannel member with visible DataChannelEntry[] in HF_SyncReply
• Added missing Register_Class() for HF_ReFire_Wrapper

Testing & Quality

• Modified fingerprint test simtime limit to 130s and updated fingerprints
