/* Host-fuzzing stub for esp_netif.h (ADR-061).
 *
 * csi_collector.c's #954 self-ping needs the STA netif handle + gateway IP.
 * In the fuzz environment there is no network stack: the handle lookup
 * returns NULL, so csi_start_self_ping() takes its no-gateway early-out and
 * the esp_ping path is never exercised (but must compile and link).
