I'm no expert in this area, I'd trust the opinion of the embedded folks (adding Florian as well) more than myself. It's unclear to me why we'd wait_for_init_devices_probe() after the first failed iteration, sleep, and then allow 11 more iterations with wait_for_device_probe(). Let me also add Thomas since he wrote e2ffe3ff6f5e ("net: ipconfig: Wait for deferred device probes").
