Pull request overview
Adds basic spoof/loopback suppression for incoming UDP-multicast mesh packets, improving safety when bridging packets over LAN in Meshtastic’s UDP transport path.
Changes:
- Rejects received UDP packets that claim a local origin (
from == 0orfrom == local node). - Logs and drops suspected spoofed local-origin packets before enqueuing to the router.
