3695137619 Let the clock servo know the expected sync interval.
This patch adds a new servo method to let the algorithm know about the
master clock's reported sync message interval. This information can be
used by the servo to adapt its synchronization parameters.

ab29608e0b Modify servo_sample() to accept integer values.
Current date stored in nanoseconds doesn't fit in 64-bit double format.
Keep the offset and the time stamp in integer nanoseconds.

d67892abd7 ptp4l: modify servo setup to take an enum rather than string
passing a string as the servo type seems ugly when there are only a few
choices. This patch modifies the servo_create to take an enum instead.

87e61f9770 Let the clock servo know about the expected time stamp quality.
If software time stamping is to be used, then the servo will want to
have appropriate filtering.
