-/* ---- RuView#521/#954: connected-STA CSI traffic source (additive) ----
- *
- * The ESP32 CSI engine only produces CSI for received OFDM frames (L-LTF/HT-LTF).
- * On a quiet network — or on a display-enabled build where the #893 MGMT->MGMT+DATA
- * promiscuous upgrade is skipped (has_display=true) — the only CSI-eligible frames
- * are sparse beacons (often non-OFDM DSSS), so wifi_csi_callback can starve to
- * yield=0pps -> DEGRADED -> motion/presence=0 (#521, #954).
- *
- * This guarantees a ~50 Hz OFDM unicast floor by pinging the STA's own gateway:
- * the router's ICMP echo replies are OFDM frames destined to this station, which
- * drive the CSI engine regardless of promiscuous filter state or ambient traffic.
- * It is ADDITIVE — promiscuous capture (#396/#893) is left fully intact so
- * multistatic/multi-node sensing still hears other stations' frames. Mirrors
- * Espressif's esp-csi csi_recv_router reference.
