[ixp1200] IXP1200 timings.

[Shyamal Pandya]

The FBI units cycle counter can be read from the microengines using the csr 
instruction.. I have used the instruction.

The paper mentions "instrumenting the code to use the IXP1200 cycle counter"
Is that what you mean by that, or are you doing anything else?
