[c-nsp] 28xx performance question

[Brian Vowell]

Don't quote me, but I'd assume the IDB limit would be based on physmem.  
I'm running 512MB in both of ours, and our three BGP tables (which 
account for eight seperate peers) never consumes more than about 80MB.  
We've got a full 200MB free.  Both the 2811 and 2821 that we have 
support Turbo ACL's.
