The spec explicitly say that VF RSS *is* supported in particular in the 
table mentioned above.
What your code is doing is that in case of 16 VFs u setup a 32 pools 
configuration and use only 16 out of them.

Like I said before, trying to guess what user wants is a way to making a 
code that is very hard to use and to maintain. Pls., just return an 
error and let the user code deal with it the way he/she really wants and 
not the way u *think* he/she wants.
