[lwip-users] ARP requests crashing stack

The lwip stack stops responding completely when an IPscan on the subnet is 
performed. This spews out a series of ARP requests. 

It looks like the Ethernet MAC stops generating interrupts because 
ethernetif_input() is no longer called.
lwIPstats() reports an ETHARP drop and lenerr which makes me think the MAC is 
is not being serviced fast enough.
I'm using a modified STR9 demo from FreeRTOS with lwip 1.4.0.
My lwipopts.h settings are using the defaults for the most part.

Anyone else have this issue?
