That's really odd if you see the same problem with different
HW/drivers.

When I run "ptp4l -6 -S -i ens5 -m", ss reports only IPv6 sockets for
ptp4l:
# ss -lup | grep ptp4l
UNCONN 0 0 ::%ens5:ptp-event :::*
users:(("ptp4l",pid=5862,fd=10))
UNCONN 0 0 ::%ens5:ptp-general :::*
users:(("ptp4l",pid=5862,fd=11))
