With the default setting, dldo3 is regulated at 2.9v which seems sufficient for the PHY but the aforementioned commit drops it to 2.5V which is insufficient. Note that this behaviour is random for all BPIM3. Some work with 2.5V, but some don't. Finnaly, someone from Bananapi confirmed that this regulator must be set to 3.3V.
