There's plenty of people using lwIP with DHCP without problems, so I
think there's something wrong with the way you're trying to call
netif_add().  Rather than passing NULL arguments, I would try supplying
pointers to values that are zeroed, and let the DHCP code set them when
it gets the right address.
