In addition to what mebrown said, there _is_ a fast instruction for inverse square root (rsqrtss).
In general, packet processing is not dominated by a single operation; it's more like various small tasks all over, so one specific instruction is unlikely to help a whole lot. But CPUs just getting generally faster helps, of course (even though there was a long time where progress was rather disappointing).
