.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.
