On Puma v2.1 with a KSZ9031, the Ethernet PHY often doesn't detect the link in the 4-second default timeout.
After some boot-loop test for about a thousand boots, 70% were below 10s, 90% below 15s and 100% below 30s. Let's play it safe and make it 30s so that hopefully all links that should be detected are.
