Yes, thats true. Forgot that I have an own TLV on the side, making it possible
to change
settings by reading the configuration file again and

This series really needs a cover letter that describes the use case(s)
in some detail. As it stands, we are all wondering, "why would

If synchronizing a PHC to the system clock, use one of the
PTP_SYS_OFFSET ioctls (if supported) to measure the offset between the
two clocks. Negate the offset and switch the timestamp before passing
them to the servo.
This makes the synchronization between PHC and system clock symmetric.

This series adds support for more accurate measurement of the offset
between a PHC and the system clock.
The first patch fixes a valgrind warning.
The second, third and fourth patches add support for new ioctls.
The fifth patch improves accuracy of PHC synchronization.
The sixth patch fixes a
A clock that cannot be adjusted has no servo. Check if a servo is
present before updating the clock.

This ioctl uses cross timestamping for a more accurate measurement of
the offset. It is supported on some onboard Intel NICs using the e1000e
driver and a virtual PHC with the ptp_kvm driver.

This is a more accurate variant of the the PTP_SYS_OFFSET ioctl, which
will probably be supported in future kernel versions.

The kernel supports different PTP_SYS_OFFSET* ioctls. Use the sysoff
enum to allow selecting between them in sysoff_measure().
