This patch addresses the bug observed in ptp4l in slaveOnly mode. When the upstream master is no longer available (not reachable), the slave moves to LISTENING state. However, the gmIdentity is not updated in ptp4l. This causes gmPresent reported as true despite GM being non-reachable in pmc commands.
