Apologies for getting late to this change given that the change has 
already been merged.
I'm wondering why is it that link_gen has to be used in deriving the 
index instead of directly using '1' as the index?
Infact the for link speed greater than 2, accesses go beyond n_fts[] 
array boundaries.
Since the if() check is done based on a non-zero value of pci->n_fts[1], 
shouldn't the same be used for programming also?
