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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
