I'm looking for information about the Ethernet chip on the Orange Pi 5. I need an SBC that has PTP hardware timestamp support (IEEE 1588). According to OrangePi.org, the Orange Pi 5 has the Motorcomm YT8531C, but I have not been able to find documentation that provides the answer about hardware PTP support. Most likely it does not, but I'd like to confirm on an actual device before purchasing one.

If you have an Orange Pi 5, you can test this with this command:

ls /sys/class/net |xargs -n1 ethtool -T

If there is someone that can post the output of this command, I would appreciate it very much. Sorry for the odd question, this is the best StackExchange site I could find to ask this question. I would ask on the OrangePi forum, but it doesn't run HTTPS, so I'd rather not create an account there.

A kind user on the armbian forum, @royk, ran the ethtool command, and posted the output which shows:
