+~~~~~~~~~~~~~~~~~~~~~~
+
+Set the link status monitoring polling period in milliseconds for a bonding devicie.
+
+This adds support for PMD slave devices which do not support link status interrupts.
+When the mon_period is set to a value greater than 0 then all PMD's which do not support
+link status ISR will be queried every polling interval to check if their link status has changed.
