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

[Sukumar Subburayan]

The 'show interface capabilities..' command currently supports only 
one-level (ie first ASIC) of port-ASIC group mapping.

For linecards with multiple-level ASICs, the 'Ports on ASIC' refers to the 
group of ports connected to the top-level (like in the example give in the 
thread) ASIC.

There is enhancement bug filed (CSCek37940), to include all level of ASIC 
grouping.

Once the fix is available in a CCO release, the output would look like:

Ports on ASIC (Sub-ASIC): 1-24 (1-8)
