Napatech as a Plugin
====================

Suricata 8.0 moves Napatech packet capture support to a dynamically loaded
plugin. For convenience, this plugin is still bundled with Suricata, but it
may be removed from the Suricata source tree into its own repository in a
future release.

Upgrading
---------

Suricata 8.0 continues to respect the ``--enable-napatech`` compile time
option, as well as the ``--napatech`` command-line options, and also
the ``napatech`` section of the configuration file.

.. note:: When the Napatech capture plugin is eventually removed from the
          Suricata source tree these options may be removed and/or changed
          as this would allow the Napatech capture plugin to have its own
          release cycle and make changes independent of Suricata.

However, the ``napatech`` capture plugin must be loaded before it can be
used. If doing a fresh build of Suricata with Napatech support, the
``suricata.yaml`` configuration file should be configured to load the
plugin already, for example::

  plugins:
    - /usr/lib/suricata/napatech.so

If you are upgrading, you will need to add the location of
``napatech.so`` to the ``plugins`` section of your ``suricata.yaml``
manually, as shown above.

Existing Napatech command-line options and configuration should continue to work.

Caveats
-------

Currently building the Napatech capture plugin is not compatible with the
``--disable-shared`` configure argument.
