install it from the ports collection. Details of getting and using the ports

Installing the DPDK FreeBSD Port

can be installed using the commands:
.. code-block:: console
- root@host:~ # cd /usr/ports/net/dpdk
+ cd /usr/ports/net/dpdk
- root@host:~ # make install
+ make install
After the installation of the DPDK port, instructions will be printed on
how to install the kernel modules required to use the DPDK. A more
complete version of these instructions can be found in the sections
:ref:`loading_contigmem` and :ref:`loading_nic_uio`. Normally, lines like
-those below would be added to the file "/boot/loader.conf".
