> +--------------
> +
> +In order to enable this virtual crypto PMD, user must:
> +
> +* Build the multi buffer library (explained in Installation section).
> +
> +To use the PMD in an application, user must:
> +
> +* Call rte_vdev_init("crypto_chacha20_poly1305") within the application.
> +
> +* Use --vdev="crypto_chacha20_poly1305" in the EAL options, which will
> call
> + rte_vdev_init() internally.
> +
> +The following parameters (all optional) can be provided in the previous two
> calls:
> +
> +* socket_id: Specify the socket where the memory for the device is going to
> be allocated
> + (by default, socket_id will be the socket where the core that is creating the
> PMD is running on).
> +
> +* max_nb_queue_pairs: Specify the maximum number of queue pairs in the
> device (8 by default).
> +
> +* max_nb_sessions: Specify the maximum number of sessions that can be
> created (2048 by default).
> +
> +Example:
> +
> +.. code-block:: console
> +
> + --vdev="crypto_chacha20_poly1305,socket_id=0,max_nb_sessions=128"

Ok. Split the test app changes in a separate patch.

+Chacha20-poly1305 Crypto Poll Mode Driver
+=========================================
+
+The Chacha20-poly1305 PMD provides poll mode crypto driver support for
+utilizing `Intel IPSec Multi-buffer library <https://github.com/01org/intel-ipsec-mb>`_.
+
+Features
+--------
+
+Chacha20-poly1305 PMD has support for:
+
+AEAD algorithms:
+
+* RTE_CRYPTO_AEAD_CHACHA20_POLY1305
+
+
+Installation
+------------
+
+To build DPDK with the Chacha20-poly1305 PMD the user is required to download
+the multi-buffer library from `here <https://github.com/01org/intel-ipsec-mb>`_
+and compile it on their user system before building DPDK.
+The latest version of the library supported by this PMD is v1.0, which
+can be downloaded from `<https://github.com/01org/intel-ipsec-mb/archive/v1.0.zip>`_.
+
+After downloading the library, the user needs to unpack and compile it
+on their system before building DPDK:
+
+.. code-block:: console
+
+ make
+ make install
+
+The library requires NASM to be built. Depending on the library version, it might
+require a minimum NASM version (e.g. v0.54 requires at least NASM 2.14).
+
+NASM is packaged for different OS. However, on some OS the version is too old,
+so a manual installation is required. In that case, NASM can be downloaded from
+`NASM website <https://www.nasm.us/pub/nasm/releasebuilds/?C=M;O=D>`_.
+Once it is downloaded, extract it and follow these steps:
+
+.. code-block:: console
+
+ ./configure
+ make
+ make install
+
+.. note::
+
+ Compilation of the Multi-Buffer library is broken when GCC < 5.0, if library <= v0.53.
+ If a lower GCC version than 5.0, the workaround proposed by the following link
+ should be used: `<https://github.com/intel/intel-ipsec-mb/issues/40>`_.
+
+As a reference, the following table shows a mapping between the past DPDK versions
+and the external crypto libraries supported by them:
+
+.. _table_zuc_versions:
+
+.. table:: DPDK and external crypto library version compatibility
+
+ ============= ================================
+ DPDK version Crypto library version
+ ============= ================================
+ 21.11+ Multi-buffer library 1.0*
+ ============= ================================
+
+\* Multi-buffer library 1.0 or newer only works for Meson but not Make build system.
+
+Initialization
+--------------
+
+In order to enable this virtual crypto PMD, user must:
+
+* Build the multi buffer library (explained in Installation section).
+
+To use the PMD in an application, user must:
+
+* Call rte_vdev_init("crypto_chacha20_poly1305") within the application.
+
+* Use --vdev="crypto_chacha20_poly1305" in the EAL options, which will call
+ rte_vdev_init() internally.
+
+The following parameters (all optional) can be provided in the previous two calls:
+
+* socket_id: Specify the socket where the memory for the device is going to be allocated
+ (by default, socket_id will be the socket where the core that is creating the PMD is running on).
+
+* max_nb_queue_pairs: Specify the maximum number of queue pairs in the device (8 by default).
+
+* max_nb_sessions: Specify the maximum number of sessions that can be created (2048 by default).
+
+Example:
+
+.. code-block:: console
+
