 If set the outer to 0 and set the inner to 10, it means finding the packet which has double tag and its inner tag VID=10.
 If set the outer to 10 and set the inner to 20, it means finding the packet which has double tag and its outer VID=10 (SVID), inner VID=20 (CVID).

+The data type will also be used to provide the new dot1q header setting after the vlan stacking rule by the attribute, SAI_VLAN_STACK_ATTR_APPLIED_VLAN_ID.
 If the action is PUSH, the value of the "outer" will be used to create an outer dot1q header on the packet.
 If the action is SWAP, the original dot1q header will be replaced with "outer", "inner" or both. Depends on the attribute setting.
