5. Create a CSAP on Tester to send packets to iut_addr2.

6. Send untagged packet when no VLANs are added yet.

7. Send a packet to vlan_a_id when no VLANs are added yet.

9. Send untagged packet when VLANs are added.

10. Send a packet to added VLAN vlan_a_id.

11. Send a packet to added VLAN vlan_b_id.

12. Delete VLAN vlan_a_id from the iut_if.

13. Send a packet to still added VLAN vlan_b_id.

14. Send a packet to just removed VLAN vlan_a_id.
