Dear Team,
As part of PTP implementation for a client we are using LinuxPTP (version 1.4)
for validation, Currently are trying to setup IPv6 interface environment (with
HW timestamping) where we are observing that LinuxPTP Slave daemon is not
processing the IPv6 packets. (Please note that there are no intermediate nodes
or clocks in between Master and Slave daemons).
In the same environment IPv4 and Mac based PTP sync is working fine.
Have attached the Linux environment details which we are using for testing.
Please check and suggest if we are missing any configuration required.
Regards,
Karthikeyan.
