They thought they needed to inspect/act on some/all ICMP traffic at the 
time they designed the forwarding ASIC, so they just punted all ICMP to 
CPU.

These platforms have other shortcomings from being designed in the late 
90:ties, but I know people who still have them in production because if 
you don't have too many flows (they have a per-destination based 
forwarding cache), they still work fairly well.
