   I am not so sure with that 6% difference there is no other bug lurking
   there; 6% seems too large for an extra two PCI transactions per packet.

{in,out}{b,w,l}() operations have a fixed timing, therefore his
results doesn't sound that far off.

It is also one of the reasons I suspect Andrew saw such bad results
with 3c59x, but probably that is not the only reason.
