15.3.4 Dot1q-tunnel Troubleshooting
 Enabling dot1q-tunnel on Trunk port will make the tag of the data packet unpredictable which is not
required in the application. So it is not recommended to enable dot1q-tunnel on Trunk port.
 Enabled with STP/MSTP is not supported.
 Enabled with PVLAN is not supported.
