+ * During warm boot, when switch restarted we expect that switch will have the
+ * same number of objects like before boot, and all vendor OIDs (RIDs) will be
+ * exactly the same as before reboot.
+ *
+ * If OIDs are not the same, then this is a vendor bug.
+ *
+ * Exception of this rule is when orchagent will be restarted and it will add
+ * some more objects or remove some objects.
+ *
+ * We take special care here about INGRESS_PRIORIRITY_GROUPS, SCHEDULER_GROUPS
+ * and QUEUES, since those are internal objects created by vendor when switch
+ * is instantiated.
