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.
