.TP
+.B net_sync_monitor
+Enables the NetSync Monitor (NSM) protocol. The NSM protocol allows a
+station to measure how well another node is synchronized. The monitor
+sends a unicast delay request to the node, which replies
+unconditionally with unicast delay response, sync, and follow up
+messages. If the monitor is synchronized to the GM, it can use the
+time stamps in the message to estimate the node's offset. This option
+requires that the 'hybrid_e2e' option be enabled as well.
+The default is 0 (disabled).
+.TP
.B ptp_dst_mac
The MAC address to which PTP messages should be sent.
Relevant only with L2 transport. The default is 01:1B:19:00:00:00.
