[nsp] Difference Between LS1010 FC1 and FPGA

[Brian]

I am trying to find out what a LS1010 "FPGA" Feature Card is.  I 
normally see feature cards
on ASP modules show up as "FeatureCard1" or "FC-PFQ", both of which I 
understand and
know the differences.  But I have seen some ASP feature cards show up 
as "FPGA"  (in the
output of "show hardware") and was curious if this is a different 
animal than a normal FC1?

I searched cisco.com for an explaination but could not come up with 
anything.
