It seems only a few cards can do this though. It would be nice. But then what clock would they use to timestamp the packets. If it is an onboard network card clock one would then also have to discipline that network card clock ( or at least calbrate it, and as we know that calibration changes so it would have to be another continuous calibration of that clock.) > > (On FreeBSD these interrupt mitigation techniques should be tweakable > using the sysctls under the dev.em sysctl tree.) > > David. _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
