PtpClockStateType
This object specifies the Clock state returned by a PTP engine
which was described earlier.
Freerun state. Applies to a slave device that is not locked to
a master. This is the initial state a slave starts out with
when it is not getting any PTP packets from the master, or
because of some other input error (erroneous packets, etc).
Holdover state. In this state the slave device is locked to a
master but communication with the master has been lost or the
timestamps in the PTP packets are incorrect. Since the
slave was previously locked to the master, it can run in this
state, with similar accuracy for some time. If communication
with the master is not restored for an extended period
(dependent on the clock implementation), the device should move
to the FREERUN state.
Acquiring state. The slave device is receiving packets from a
master and is trying to acquire a lock.
Freq_locked state. Slave device is locked to the Master with
respect to frequency, but not phase aligned.
Phase_aligned state. Locked to the master with respect to
frequency and phase.
