Enable for a Monitored Node

On the PTP slave server to be monitored, the following options should be enabled in the PTP generic section of the sfptpd config file:

# PTP Generic Configuration
#
[ptp]
mon_monitor_address <address of remote monitoring station interface>
mon_rx_sync_timing_data
mon_rx_sync_computed_data
mon_tx_event_timestamps

If address is omitted, PTP Signaling messages from the monitored slave will be multicast.
