- Add ip/gw/subnet/dns get/set commands with SPIFFS persistence
- Implement reconfigureEthernet() method for runtime config
- Fix TCP_CONSOLE_PORT conditional compilation
- Update platformio.ini for consistency (USE_ETHERNET)
- Document Ethernet settings and get bridge.type command
- Fixes #2196 #2197 hardware and console dependencies
