+ Log optimization for ptp4l in jbod and client only mode (clientOnly=1 and boundary_clock_jbod=1)
+
+ The LISTENING port prints continuously
+ "selected best master clock 000000.0000.000003
+ updating UTC offset to 37"
+
+ We limited the log such that now it prints only when there is a
+ change in the best-master clock.

+
+ Log optimization for ptp4l in jbod and client only mode (clientOnly=1 and boundary_clock_jbod=1)
+
+ The port other than SLAVE (LISTENING port) prints an error
+ "port 1: master state recommended in slave only mode
+ ptp4l[1205469.356]: port 1: defaultDS.priority1 probably misconfigured"
+ for every ANNOUNCE RECEIPT Timeout.
+
+ This log is printed when the event EV_RS_MASTER is thrown
+ in clientOnly mode. But single port clientOnly mode will never
+ hit this event instead EV_RS_GRAND_MASTER will be hit.
+ EV_RS_MASTER is thrown when clientOnly=1 and boundary_clock_jbod=1
+ which results in continuous printing. So EV_RS_MASTER check when
+ clientOnly=1 to print this error can be avoided.
