Hi, Based on your comments, we are pulling back this change. For the issues we saw with the clientOnly=1 and boundary_clock_jbod=1, we have sent out a new patch fixing them alone. Thank you for your feedback. Thanks, Amar B S -Original Message- From: Ramana Reddy Sent: 28 April 2021

This change brings slave clock jbod feature which allows ptp4l to work as a Ordinary Subordinate/Slave clock using "just a bunch of devices" that are not synchronized to each other but a collection of clocks synchronized by an external source.The best master will be decided by BMCA among the
