+KASUMI Crypto Poll Mode Driver
+===============================
+
+The KASUMI PMD (**librte_pmd_kasumi**) provides poll mode crypto driver
+support for utilizing Intel Libsso library, which implements F8 and F9 functions
+for KASUMI UEA1 cipher and UIA1 hash algorithms.
+
+Features
+--------
+
+KASUMI PMD has support for:
+
+Cipher algorithm:
+
+* RTE_CRYPTO_SYM_CIPHER_KASUMI_F8
+
+Authentication algorithm:
+
+* RTE_CRYPTO_SYM_AUTH_KASUMI_F9
+
+Limitations
+-----------
+
+* Chained mbufs are not supported.
+* KASUMI(F9) supported only if hash offset field is byte-aligned.
+
+Installation
+------------
+
+To build DPDK with the KASUMI_PMD the user is required to download
+the export controlled ``libsso_kasumi`` library, by requesting it from
+`<https://networkbuilders.intel.com/network-technologies/dpdk>`_.
+Once approval has been granted, the user needs to log in
+`<https://networkbuilders.intel.com/dpdklogin>`_
+and click on "Kasumi Bit Stream crypto library" link, to download the library.
+After downloading the library, the user needs to unpack and compile it
+on their system before building DPDK::
+
+ make kasumi
+
+Initialization
+--------------
+
+In order to enable this virtual crypto PMD, user must:
+
+* Export the environmental variable LIBSSO_KASUMI_PATH with the path where
+ the library was extracted (kasumi folder).
+
+* Build the LIBSSO library (explained in Installation section).
+
+* Set CONFIG_RTE_LIBRTE_PMD_KASUMI=y in config/common_base.
+
+To use the PMD in an application, user must:
+
+* Call rte_eal_vdev_init("cryptodev_kasumi_pmd") within the application.
+
+* Use --vdev="cryptodev_kasumi_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).
+
+Example:
+
+.. code-block:: console
+
+ ./l2fwd-crypto -c 40 -n 4 --vdev="cryptodev_kasumi_pmd,socket_id=1,max_nb_sessions=128"
