+show device info
+~~~~~~~~~~~~~~~~
+
+Show general information about devices probed::
+
+ testpmd> show device info (<identifier>|all)
+
+For example:
+
+.. code-block:: console
+
+ testpmd> show device info net_pcap0
+

testpmd> port close (port_id|all)
+port reset
+~~~~~~~~~~
+
+Reset all ports or a specific port::
+
+ testpmd> port reset (port_id|all)
+
+User should stop port(s) before resetting and (re-)start after reset.

port config - queue ring size
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is equivalent to the ``--max-pkt-len`` command-line option.
-port config - CRC Strip
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Set hardware CRC stripping on or off for all ports::
-
- testpmd> port config all crc-strip (on|off)
-
-CRC stripping is on by default.
-
-The ``off`` option is equivalent to the ``--disable-crc-strip`` command-line option.
-
-port config - scatter
-~~~~~~~~~~~~~~~~~~~~~~~
-
-Set RX scatter mode on or off for all ports::
-
- testpmd> port config all scatter (on|off)
-
-RX scatter mode is off by default.
-
-The ``on`` option is equivalent to the ``--enable-scatter`` command-line option.
-
-port config - RX Checksum
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Set hardware RX checksum offload to on or off for all ports::
-
- testpmd> port config all rx-cksum (on|off)
-
-Checksum offload is off by default.
-
-The ``on`` option is equivalent to the ``--enable-rx-cksum`` command-line option.
-
-port config - VLAN
-~~~~~~~~~~~~~~~~~~
-
-Set hardware VLAN on or off for all ports::
-
- testpmd> port config all hw-vlan (on|off)
-
-Hardware VLAN is off by default.
-
-The ``on`` option is equivalent to the ``--enable-hw-vlan`` command-line option.
-
-port config - VLAN filter
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Set hardware VLAN filter on or off for all ports::
-
- testpmd> port config all hw-vlan-filter (on|off)
-
-Hardware VLAN filter is off by default.
-
-The ``on`` option is equivalent to the ``--enable-hw-vlan-filter`` command-line option.
-
-port config - VLAN strip
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-Set hardware VLAN strip on or off for all ports::
-
- testpmd> port config all hw-vlan-strip (on|off)
-
-Hardware VLAN strip is off by default.
-
-The ``on`` option is equivalent to the ``--enable-hw-vlan-strip`` command-line option.
-
-port config - VLAN extend
-~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Set hardware VLAN extend on or off for all ports::
-
- testpmd> port config all hw-vlan-extend (on|off)
-
-Hardware VLAN extend is off by default.
-
-The ``on`` option is equivalent to the ``--enable-hw-vlan-extend`` command-line option.
-
port config - Drop Packets
~~~~~~~~~~~~~~~~~~~~~~~~~~
-Set packet drop for packets with no descriptors on or off for all ports::
+Enable or disable packet drop on all RX queues of all ports when no receive buffers available::
testpmd> port config all drop-en (on|off)
-Packet dropping for packets with no descriptors is off by default.
+Packet dropping when no receive buffers available is off by default.
The ``on`` option is equivalent to the ``--enable-drop-en`` command-line option.

+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.
+
Link Bonding Functions
----------------------
- ``data {unsigned}``: metadata value.
+- ``gtp_psc``: match GTP PDU extension header with type 0x85.
+
+ - ``pdu_type {unsigned}``: PDU type.
+ - ``qfi {unsigned}``: QoS flow identifier.
