[Linuxptp-users] PTP Clock completely wrong on a Intel 82579L

[Norbert L. <nol...@gm...>]

Hello,

I tried enabling PTP in a local Network, there where just nonsensical
value all the time.
Looking with Wireshark at the communication, the master sends out a
"Followup" Packet every second (very precisely), which contains the
internal time.

This time increases almost by 4 seconds every time.

The Hardware is an Intel 82579L, soldered on the motherboard. Any idea
if this is a software issue, a systematic hardware bug or something
like a wrong reference clock?

OS is an actual Linux Debian 9 AMD64 with Linux 4.9

Kind Regards,
Norbert
