STM32F107 issue: Lan configuration fails if no cable is pluged

I've noticed an ugly thing while working with the stm32C10-Eval Board and Ethernet. In case the LAN cable is plugged, the PHY gets well initialized. But if no LAN cable is plugged in while the power on, the function ETH_Init(&ETH_InitStructure, PHY_ADDRESS)) returns "0" and the board is not "offline". Is there a chance to get the LAN working on a later cable plugin? The ETH_Init function is original from ST. This behavior occurs on both Phy modes RMI/MII. Do the Phy need some traffic to generate internal clock which are needed on the initialization?

Best Regards
