Sorry for getting back late to you. It did not compute when I read your email the first time around, then I let it sit for a while. On Thu, Nov 05, 2020 at 09:18:04PM +0100, Christian Eggers wrote:quoted
unfortunately I made a mistake when testing. Actually the timestamp *must* be moved from the correction field (negative) to the egress tail tag.That doesn't sound very good at all.
I think that is no drawback. It is implemented and works.
I have a simple question. Can your driver, when operating as a PTP master clock, distribute a time in 2020 into your network? (you can check with "phc_ctl /dev/ptp0 get")
# phc_ctl /dev/ptp2 get phc_ctl[2141.093]: clock time is 1605018671.788481458 or Tue Nov 10 14:31:11 2020 The KSZ PTP clock has 32 bit seconds (and 30 bit nanoseconds). I hope I can send the new series tonight. Had today no 5 minutes without the telephone ringing...
