Dear gentlemen,
I've been following your debate, and while it's a sin to comment off
topic, it's difficult for me to hold back the following smirk:

I've never heard of this symptom being reported before.
My gut reaction is that this is caused by code in e1000e_read_systim, which
reads the SYSTIME multiple times. I am suspicious that multiple readings is
somehow impacting the clock time, which

Hi everyone,
While developing a PTP slave using the Linux PHC, I noticed, that everytime I call clock_gettime with the PHC ID, the time on the PHC jumps or at least changes by around 200-300ns. I noticed this, because I have implemented an algorithm reading the PHC time ten times in a row to find a
