[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?
