This enables the clock to provide time information using a single event message. If disabled the
clock will provide time information using the combination of an event message and a subsequent
general message.
This parameter selects the delay measurement. 0 = End-to-end; 1 = Peer-to-peer
End-to-end is the delay mechanism between slave clocks and the master clock.
Peer-to-peer delay mechanism provides not only the PTP event transit time information, but also
provides the corrections for the propagation delay of the link connected to the port receiving the
PTP event message.
This parameter controls the rate at which PTP Sync frames are sent. The message rate is
determined by raising 2 to the power of this parameter. E.g the default value of -2, results in four
sync messages per second.
