- Add rx_dup_count (local) and tx_dup_count (remote via ACK) to ETCP_CONN
- Extend ACK section format: add 16-bit rx_dup_count after last_delivered_id
- Reconstruct 32-bit tx_dup_count from received 16-bit diff
- Update etcpmon protocol and control_server to expose counters
- Update packet dumper for new ACK format
- utun_update.sh: Shell script for updating single instance
* fast mode: git pull + make clean + make
* full mode: complete rebuild with autotools
* Auto-detects project root from script location
* Handles PID-based process stop/start
* Supports Linux and BSD (nproc/sysctl)
* Returns proper exit codes (0-4)
- mass_update.py: Python script for parallel SSH updates
* Parallel execution via ThreadPoolExecutor
* Configurable via JSON (~/.utun_servers.json)
* Supports custom port/user per server
* Timeout and error handling
* Summary output per server
Tools for remote mass deployment of uTun updates via SSH.
- Add timeout_heap_get_size() to get active timer count
- Add global counters in memory_pool: g_total_free and g_total_allocated
- Simplify busy memory calculation to single formula:
busy = memory_pool_get_total_allocated() - memory_pool_get_total_free_blocks()
- Add new IDC_EDIT_ACTIVE_TIMEOUTS and IDC_EDIT_BUSY_MEMORY to GUI
- Added queue bytes/packets for all 6 ETCP queues
- Added error counters: reinit_count, reset_count, pkt_format_errors
