This patch series includes unit test, openssl pmd and documentation patches
for asymmetric crypto support in lib cryptodev framework.
These are based on asym patch V1 series

Initial unit test case to test openssl PMD asym crypto
operations. Test case invoke asymmetric operation on DPDK
Openssl PMD and cross-verify results via Openssl SW library.
Tests have been verified with openssl 1.0.2m release.
Tested for:
* RSA Encrypt, Decrypt, Sign and Verify using pre-defined
test vectors
* Modular Inversion and Exponentiation using pre-defined
test vectors
* Deiffie-Hellman Public key generation using pre-defined
private key and dynamically generated test vectors
* Deffie-hellman private key generation using dynamically
generated test vectors
* Deffie-hellman private and public key pair generation
using xform chain and using dynamically generated test
vectors
* Deffie-hellman shared secret compute using dynamically
generated test vectors
* DSA Sign and Verification
Deffie-hellman testcases use run-time generated test params,
thus may take some time for execution.

Asymmetric Cryptography
-----------------------
-Asymmetric functionality is currently not supported by the cryptodev API.
+The cryptodev library currently provides support for the following asymmetric
+Crypto operations; RSA, Modular exponentiation and inversion, Deffie-hellman
+public and/or private key generation and shared secret compute, DSA Signature
+generation and verification.
+
+Session and Session Management
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sessions are used in asymmetric cryptographic processing to store the immutable
+data defined in asymmetric cryptographic transform which is further used in the
+operation processing. Sessions typically stores information, such as, public
+and private key information or domain params or prime modulus data i.e. immutable
+across data sets. Crypto sessions cache this immutable data in a optimal way for the
+underlying PMD and this allows further acceleration of the offload of Crypto workloads.
+
+Like symmetric, the Crypto device framework provides APIs to allocate and initizalize
+asymmetric sessions for crypto devices, where sessions are mempool objects.
+It is the application's responsibility to create and manage the session mempools.
+Application using both symmetric and asymmetric sessions should allocate and maintain
+different sessions pools for each type.
+
+An application can use ``rte_cryptodev_get_asym_session_private_size()`` to
+get the private size of asymmetric session on a given crypto device. This
+function would allow an application to calculate the max device asymmetric
+session size of all crypto devices to create a single session mempool.
+If instead an application creates multiple asymmetric session mempools,
+the Crypto device framework also provides ``rte_cryptodev_get_header_session_size()`` to get
+the size of an uninitialized session.
+
+Once the session mempools have been created, ``rte_cryptodev_asym_session_create()``
+is used to allocate an uninitialized asymmetric session from the given mempool.
+The session then must be initialized using ``rte_cryptodev_asym_session_init()``
+for each of the required crypto devices. An asymmetric transform chain
+is used to specify the operation and its parameters. See the section below for
+details on transforms.
+
+When a session is no longer used, user must call ``rte_cryptodev_asym_session_clear()``
+for each of the crypto devices that are using the session, to free all driver
+private asymmetric session data. Once this is done, session should be freed using
+``rte_cryptodev_asym_session_free()`` which returns them to their mempool.
+
+Asymmetric Sessionless Support
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Currently asymmetric crypto framework does not support sessionless.
+
+Transforms and Transform Chaining
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Asymmetric Crypto transforms (``rte_crypto_asym_xform``) are the mechanism used
+to specify the details of the asymmetric Crypto operation. Next pointer within
+xform allows transform to be chained together. Also it is important to note that
+the order in which the transforms are passed indicates the order of the chaining.
+
+Not all asymmetric crypto xforms are supported for chaining. Currently supported
+asymmetric crypto chaining is Deffie-hellman private key generation followed by
+public generation. Also, currently API does not support chaining of symmetric and
+asymmetric crypto xfroms.
+
+Each xform defines specific asymmetric crypto algo. Currently supported are:
+* RSA
+* Modular operations (Exponentiation and Inverse)
+* Deffie-hellman
+* DSA
+* None - special case where PMD may support a passthrough mode. More for diagonistic purpose
+
+.. code-block:: c
+
+ struct rte_crypto_asym_xform {
+ struct rte_crypto_asym_xform *next;

+ /**< DH xform parameters */
+
+ struct rte_crypto_dsa_xform dsa;
+ /**< DSA xform parameters */
+ };
+ };
+
+Asymmetric Operations
+~~~~~~~~~~~~~~~~~~~~~
+
+The asymmetric Crypto operation structure contains all the mutable data relating
+to asymmetric cryptographic processing on an input data buffer. It uses either
+RSA, Modular, Deffie-hellman or DSA operations depending upon session it is attached
+to.
+
+Every operation must carry a valid session handle which further carries information
+on xform or xform-chain to be performed on op. Every xform type defines its own set
+of opertational params in their respective rte_crypto_xxx_op_param struct. Depending
+on xform information within session, PMD picks up and process respective op_param
+struct.
+Unlike symmetric, asymmetric operations do not use mbufs for input/output.
+They operate on data buffer of type ``rte_crypto_param``.
+
+.. code-block:: c
+
+ typedef struct rte_crypto_param_t {
+ uint8_t *data;
+ /**< pointer to buffer holding data */
+ rte_iova_t iova;
+ /**< IO address of data buffer */
+ size_t length;
+ /**< length of data in bytes */
+ } rte_crypto_param;
+
+See *DPDK API Reference* for details on each rte_crypto_xxx_op_param struct
+
+.. code-block:: c
+

+show how to setup and process asymmetric operations using cryptodev library.
+
+The following sample code shows the basic steps to compute modular exponentiation
+using 1024-bit modulus length using openssl PMD available in DPDK (performing other
+crypto operations is similar except change to respective op and xform setup).
