Thanks for your response. But my question was how do I get hold of the map
of the internal parameters on the card mapped to the memory? Meaning what
do each of the bit fields in the fxp_cb_config mean? Does Intel make such
information public and what is procedure to get this information from
vendors? 

I guess you are the best person to answer such questions. :-)
