netInitialize(); function gets crash when PHY chip not present

Hi,

We are using LPC4088 with DP83848 PHY for Ethernet communication.

If we does not supply power  to PHY or it is not present on PCB &  if call the netInitialize();  function then program crash.

After crash it does not go to any exception handler.

It should return Ethernet driver error or initialize fail error.
