It does not, most ptp implementations do their timestamp in software. whether it meets your requirements is another question entirely, I'm guessing it does not. http://ptpd.sourceforge.net/doc.html > I gather it takes a bit more to have a NIC be a PTP masterclock. > > H > _______________________________________________ > Soekris-tech mailing list > [email protected] > http://lists.soekris.com/mailman/listinfo/soekris-tech > _______________________________________________ Soekris-tech mailing list [email protected] http://lists.soekris.com/mailman/listinfo/soekris-tech
