lwIP w/ LAN91C111 initialization failure recovery

[Altera_Forum]

Hi, 

 When the Altera lwIP drivers for the LAN91C111 fail at initialization (eg. cable disconnected), lwIP seems not to be able of being recovered from the error.   Is there any procedure to follow to get it to work after the cable is connected? Any workaround?  If the cable is disconnected/connected back after the drivers have been initialized, it seems not having any problem to recover from the error condition.
