it to make it work again. Hence, zero copy may be added back later.
**VLAN strip.**
-The VLAN strip option enable/disable the VLAN strip on host, if disabled, the guest will receive the packets with VLAN tag.
-It is enabled by default.
-
-.. code-block:: console
-
- ./vhost-switch -c f -n 4 --socket-mem 1024 --huge-dir /mnt/huge \
- -- --vlan-strip [0, 1]
+VLAN strip option is removed, because different NICs have different behaviors
+when disabling VLAN strip. Such feature, which heavily depends on hardware,
+should be removed from this example to reduce confusion. Now, VLAN strip is
+enabled and cannot be disabled.
.. _vhost_app_running:
Any packets received on the NIC with these values is placed on the devices receive queue.
When a virtio-net device transmits packets, the VLAN tag is added to the packet by the DPDK vhost sample code.

-------------------------------------
-We can also use virtio-user with vhost-switch now.
-Virtio-user is a virtual device that can be run in a application (container) parallelly with vhost in the same OS,
+We can also use virtio_user with vhost-switch now.
+Virtio_user is a virtual device that can be run in a application (container) parallelly with vhost in the same OS,
aka, there is no need to start a VM. We just run it with a different --file-prefix to avoid startup failure.

There is no difference on the vhost side.
