If this is really the case, then what makes it die would be seeing traffic not destined for itself (whether unicast or broadcast). While it's not particularly desirable that lwIP might die in that situation (I don't know whether it does or not), it points to a problem not in lwIP itself, but in the underlying ethernet driver. It should not be passing packets to lwIP that are not destined for it. Perhaps it has accidentally put the card in promiscuous mode.
