Added extensive debug logging using DEBUG_* macros to both ETCP and loadbalancer modules: ETCP Module Debug Output: - Connection creation/destruction with detailed state tracking - Packet transmission/reception with ID, size, and timestamp details - ACK processing with individual ACK entry tracking - Retransmission request processing with gap detection - RTT calculation and jitter analysis with history tracking - Payload processing with duplicate detection - Measurement sections (MEAS_TS, MEAS_RESP) handling - Timer operations (retransmission, ACK scheduling) - Memory management (allocation/free operations) - Gap detection and contiguous packet delivery - Bandwidth updates and link state changes Loadbalancer Module Debug Output: - Link selection algorithm with timing calculations - Bandwidth-based load balancing decisions - Connection initialization and timeout handling - Link activity tracking and scheduling - Bandwidth measurement processing Debug Levels Available: - TRACE: Function entry/exit, packet-level details - DEBUG: Operational flow, state changes - INFO: Important events, connections, errors - WARN: Warning conditions - ERROR: Error conditions Usage examples: - ./src/utun -d 'etcp:trace' # Maximum ETCP detail - ./src/utun -d 'etcp:debug,loadbalancer:debug' # Both modules - ./src/utun -d 'all:debug' # Everything debug level This comprehensive debug output will help trace all ETCP protocol operations, packet flows, timing calculations, load balancing decisions, and state changes for thorough debugging and development of the new modules.
