+This test suite verifies that VLAN filtering, stripping, and header insertion all

+ID should be forwarded and all others should be dropped. While stripping is enabled,
+packets sent with a VLAN ID should have the ID removed and then be forwarded.
+Additionally, when header insertion is enabled packets without a
+VLAN ID should have a specified ID inserted and then be forwarded.
