That is totally not the way it should be. Please have a look at the 
ethernetif.c skeleton file to see how a driver should interact with lwIP.

LwIP will *never* call your LWIP_driver_input() function, it is up to you to 
schedule a call to this function (either by polling the driver or by getting an 
RX interrupt).
