This object controls the lifecycle of one entry in the QinQ sub-interface port-blocking table, following the standard RowStatus create/modify/delete pattern (for example createAndGo to add a rule, destroy to remove it). An admin uses it to add or remove rules that block specific combinations of interface, outer VLAN, and inner customer VLAN range on a QinQ-tunneled port. Setting this to destroy(6) on an existing entry would remove that particular VLAN-range block rule from the interface.
