+* RTE_CRYPTO_AUTH_AES_GMAC
+
+Installation
+------------
+
+To build DPDK with the AESNI_GCM_PMD the user is required to install
+the ``libisal_crypto`` library in the build environment.
+For download and more details please visit `<https://github.com/01org/isa-l_crypto>`_.
+
+Initialization
+--------------
+
+In order to enable this virtual crypto PMD, user must:
+
+* Install the ISA-L crypto library (explained in Installation section).
+
+* Set CONFIG_RTE_LIBRTE_PMD_AESNI_GCM=y in config/common_base.
+
+To use the PMD in an application, user must:
+
+* Call rte_vdev_init("crypto_aesni_gcm") within the application.
+
+* Use --vdev="crypto_aesni_gcm" 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
+
+ ./l2fwd-crypto -l 6 -n 4 --vdev="crypto_aesni_gcm,socket_id=1,max_nb_sessions=128"
