That doesn't sound right. If the
Hello,
When I lost communication with my grandmaster clock, my local ptp clock
is free running and becoming local grandmaster (the port is still slave
because of the "slaveOnly" option).
In this case, I would like phc2sys stop feeding the ntpshm to allow the
ntp daemon (chrony in this case) to

One-zero padding sounds like beginning
Ok. Thanks Jiri!
How do you think about our case? We run 1.6 on raw ethernet. This is a
normal FOLLOW-UP received with one-zero padding of 6 octets. Then ptp4l take
the padding as TLV.

Hi Steven,
Do you run with latest release? I think the problem is ptp4l takes the
length as recvmsg() - carrierHeaderLen, instead of m->header. messageLength.
Or is it the drivers responsibility to remove padding before socket?
Thanks,
Vincent
