[Linuxptp-users] time stamping

[Milutin A. <mil...@ho...>]

Hello,
I have Intel i210-t1 network card and when I enter command ethtool -T eth1 to see time stamping capabilities it says that time stamping is not supported by the card however I read in manual of my card that time stamping is supported.
When I enter a command: ptp4l -i eth1 -p /dev/ptp0 -m
it says following

ptp4l[1880.852]: selected /dev/ptp0 as PTP clock
ptp4l[1880.852]: failed to read out the clock frequency adjustment: Operation not supported
ptp4l[1880.852]: port 1: get_ts_info not supported
ptp4l[1880.853]: driver changed our HWTSTAMP options

There is /dev/ptp0 on my machine and it is valid but the problem is with network card as it says get_ts_info not supported like that time stamping is not supported but I read it in manual that it is supported.
I don't know what I'm doing wrong.
Thank you in advance,
MIlutin Aksic.
