hello,
Have a testline where ptp4l application is running as master on a server and is
connected to remote end running ptp as support/slave unit.
When the remote end application is restarted, the interface between ptp master
and support/slave ptp is going down. This is resulting in phc2sys jumping to a
huge value.

Verified the above by doing ifconfig down on master server, in this case
phc2sys remained fine.
