[c-nsp] Adjusting TCAM allocation weird behavior on 7600

[Antonio Soares]

As already mentioned, the sum should be 1024k, for example, I have this on a
SUP720-3BXL:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
sup720-3bxl#show mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
 IPv4                - 1007k 
 MPLS                - 1k (default)
 IPv6 + IP Multicast - 8k (default)
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++


1007+1+(2x8) = 1024

I read before the link you sent.

BTW, Here is the output of "sh mls cef max":

#sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
  IPv4 + MPLS         - 512k (default)
  IPv6 + IP Multicast - 256k (default)

User configured :-
---------------
  IPv4                - 600k
  MPLS                - 10k
  IPv6                - 100k
  IP Multicast        - 28k

Upon reboot :-
  IPv4                - 600k
  MPLS                - 10k
  IPv6                - 100k
  IP Multicast        - 28k
