Ethtool Sample Application
|
|
==========================
|
|
|
|
The Ethtool sample application shows an implementation of an
|
|
ethtool-like API and provides a console environment that allows
|
|
its use to query and change Ethernet card parameters. The sample
|
|
is based upon a simple L2 frame reflector.
|
|
|
|
Compiling the Application
|
|
-------------------------
|
|
|
|
To compile the sample application see :doc:`compiling`.
|
|
|
|
The application is located in the ``ethtool`` sub-directory.
|
|
|
|
Running the Application
|
|
-----------------------
|
|
|
|
The application requires an available core for each port, plus one.
|
|
The only available options are the standard ones for the EAL:
|
|
|
|
.. code-block:: console
|
|
|
|
./ethtool-app/ethtool-app/${RTE_TARGET}/ethtool [EAL options]
|
|
|
|
Refer to the *DPDK Getting Started Guide* for general information on
|
|
running applications and the Environment Abstraction Layer (EAL)
|
|
options.
|
|
|
|
Using the application
|
|
---------------------
|
|
|
|
The application is console-driven using the cmdline DPDK interface:
|
|
|
|
.. code-block:: console
|
|
|
|
EthApp>
|
|
|
|
From this interface the available commands and descriptions of what
|
|
they do as follows:
|
|
|
|
* ``drvinfo``: Print driver info
|
|
* ``eeprom``: Dump EEPROM to file
|
|
* ``module-eeprom``: Dump plugin module EEPROM to file
|
|
* ``link``: Print port link states
|
|
* ``macaddr``: Gets/sets MAC address
|
|
* ``mtu``: Set NIC MTU
|
|
* ``open``: Open port
|
|
* ``pause``: Get/set port pause state
|
|
* ``portstats``: Print port statistics
|
|
* ``regs``: Dump port register(s) to file
|
|
* ``ringparam``: Get/set ring parameters
|
|
* ``rxmode``: Toggle port Rx mode
|
|
* ``stop``: Stop port
|
|
* ``validate``: Check that given MAC address is valid unicast address
|
|
* ``vlan``: Add/remove VLAN id
|
|
* ``quit``: Exit program
|
|
|
|
|
|
Explanation
|
|
-----------
|
|
|
|
The sample program has two parts: A background `packet reflector`_
|
|
that runs on a slave core, and a foreground `Ethtool Shell`_ that
|
|
runs on the master core. These are described below.
|
|
|
|
Packet Reflector
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
The background packet reflector is intended to demonstrate basic
|
|
packet processing on NIC ports controlled by the Ethtool shim.
|
|
Each incoming MAC frame is rewritten so that it is returned to
|
|
the sender, using the port in question's own MAC address as the
|
|
source address, and is then sent out on the same port.
|
|
|
|
Ethtool Shell
|
|
~~~~~~~~~~~~~
|
|
|
|
The foreground part of the Ethtool sample is a console-based
|
|
interface that accepts commands as described in `using the
|
|
application`_. Individual call-back functions handle the detail
|
|
associated with each command, which make use of the functions
|
|
defined in the `Ethtool interface`_ to the DPDK functions.
|
|
|
|
Ethtool interface
|
|
-----------------
|
|
|
|
The Ethtool interface is built as a separate library, and implements
|
|
the following functions:
|
|
|
|
- ``rte_ethtool_get_drvinfo()``
|
|
- ``rte_ethtool_get_regs_len()``
|
|
- ``rte_ethtool_get_regs()``
|
|
- ``rte_ethtool_get_link()``
|
|
- ``rte_ethtool_get_eeprom_len()``
|
|
- ``rte_ethtool_get_eeprom()``
|
|
- ``rte_ethtool_set_eeprom()``
|
|
- ``rte_ethtool_get_module_info()``
|
|
- ``rte_ethtool_get_module_eeprom()``
|
|
- ``rte_ethtool_get_pauseparam()``
|
|
- ``rte_ethtool_set_pauseparam()``
|
|
- ``rte_ethtool_net_open()``
|
|
- ``rte_ethtool_net_stop()``
|
|
- ``rte_ethtool_net_get_mac_addr()``
|
|
- ``rte_ethtool_net_set_mac_addr()``
|
|
- ``rte_ethtool_net_validate_addr()``
|
|
- ``rte_ethtool_net_change_mtu()``
|
|
- ``rte_ethtool_net_get_stats64()``
|
|
- ``rte_ethtool_net_vlan_rx_add_vid()``
|
|
- ``rte_ethtool_net_vlan_rx_kill_vid()``
|
|
- ``rte_ethtool_net_set_rx_mode()``
|
|
- ``rte_ethtool_get_ringparam()``
|
|
- ``rte_ethtool_set_ringparam()``
