I doubt that the response time will get that low, rather the time sync
will be moved lower in the hardware stack so that the variation stays
below 1us so it can be compensated as a systematic offset. Basically a
Wi-Fi version of the hardware time stamping that a lot of NIC's do now for
PTP support. Just a guess at this point.
