[nsp] C7200 Bandwidth Points

[Dmitri Kalintsev]

Steve,

Did you try to comare the performance figures you've got with what you can
get out of two PA-FEs sitting on the same PCI bus? (I.e. both FE PAs in
either even or odd numbered slots). This might hold the key to the
performance difference you saw.
