+Device Functions

+The following sections show functions for device operations.
+
+device detach
+~~~~~~~~~~~~~
+
+Detach a device specified by pci address or virtual device args::
+
+   testpmd> device detach (identifier)
+
+Before detaching a device associated with ports, the ports should be stopped and closed.
+
+For example, to detach a pci device whose address is 0002:03:00.0.
+
+.. code-block:: console
+
+    testpmd> device detach 0002:03:00.0
+    Removing a device...
+    Port 1 is now closed
+    EAL: Releasing pci mapped resource for 0002:03:00.0
+    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218a050000
+    EAL: Calling pci_unmap_resource for 0002:03:00.0 at 0x218c050000
+    Device 0002:03:00.0 is detached
+    Now total ports is 1
+
+For example, to detach a port created by pcap PMD.
+
+.. code-block:: console
+
+    testpmd> device detach net_pcap0
+    Removing a device...
+    Port 0 is now closed
+    Device net_pcap0 is detached
+    Now total ports is 0
+    Done
+
+In this case, identifier is ``net_pcap0``.
+This identifier format is the same as ``--vdev`` format of DPDK applications.
