+
+In order to enable this virtual crypto PMD, user must:
+
+* Export the environmental variable AESNI_MULTI_BUFFER_LIB_PATH with the path
where
+ the library was extracted.
+
+* Build the multi buffer library (go to Installation section in AES-NI MB PMD
documentation).
+
+* Set CONFIG_RTE_LIBRTE_PMD_AESNI_GCM=y in config/common_base.
+
+To use the PMD in an application, user must:
+
+* Call rte_eal_vdev_init("cryptodev_aesni_gcm_pmd") within the application.
+
+* Use --vdev="cryptodev_aesni_gcm_pmd" in the EAL options, which will call
rte_eal_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).
