[c-nsp] Cisco Processing Regarding ICMP

[Phil Bedard]

Yeah, a better solution to me is to use the tcp-adjust-mss value,  
assuming this is TCP traffic and not something else.  I don't know the  
CPU limitations of that on the 7600 but it will probably end up being  
less processing power than generating an ICMP message that may never  
get to its destination.
