+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 Multi-Buffer library version supported by them:

+
+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_aesni_mb") within the application.
+
+* Use --vdev="crypto_aesni_mb" 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
+
+ ./dpdk-l2fwd-crypto -l 1 -n 4 --vdev="crypto_aesni_mb,socket_id=0,max_nb_sessions=128" \
+ -- -p 1 --cdev SW --chain CIPHER_HASH --cipher_algo "aes-cbc" --auth_algo "sha1-hmac"
+
+Extra notes
+-----------
+
+For AES Counter mode (AES-CTR), the library supports two different sizes for Initialization
+Vector (IV):
+
+* 12 bytes: used mainly for IPsec, as it requires 12 bytes from the user, which internally
+ are appended the counter block (4 bytes), which is set to 1 for the first block
+ (no padding required from the user)
