[c-nsp] WS-X6148A-GE-TX Etherchannel limit

[Tim Stevenson]

There are multiple ASICs on this card & they serve different 
functions. You can do a sh asic to see all the different ASICs on a 
particular line card. For this module, the groupings mentioned in the 
user docs & sh int cap output deal with the so-called pinnacle ASICs. 
Each of these connects to 3 mux ASICs that in turn connect 8 physical 
interfaces each.

Ports belonging to the pinnacle port groups all share certain 
characteristics, like certain qos paramters etc.
