[j-nsp] icmp problems tracing through m20's

[Harry Reynolds]

Hello,

I have not messed with mtr, but can confirm that ICMP rate limiting
on the fxp1 interface will result in some packet loss when performing
rapid (flood) pings that are destined to a PFE interface (this
traffic must transit fxp1). A recent email indicated these parameters
are now in effect; I have not confirmed:

The default rate limiting is 50 per second per logical interface
and I think 500 per box per second.
