I've experienced networks that brought high powered Coldfire based solutions
to their knees due to level of ARP traffic.  How does the MC9S12NE64 respond
with abnormally high ARP traffic?

On the upcoming LPC Ethernet solution I really hope they spend some extra
effort on Ethernet hardware filtering and IP hardware checksum via DMA.
