[PATCH v6 8/8] doc: add fips validation application guide

[Marko Kovacevic <marko.kovacevic@intel.com>]

From: "Kovacevic, Marko" <marko.kovacevic@intel.com>

Document explains how to run the fips sample app
and instructions users need to parser all the request
files and generate the response files.

+Federal Information Processing Standards (FIPS) CryptoDev Validation
+====================================================================
+
+Overview
+--------
+
+Federal Information Processing Standards (FIPS) are publicly announced standards
+developed by the United States federal government for use in computer systems by
+non-military government agencies and government contractors.
+
+This application is used to parse and perform symmetric cryptography
+computation to the NIST Cryptographic Algorithm Validation Program (CAVP) test
+vectors.
+
+For an algorithm implementation to be listed on a cryptographic module
+validation certificate as an Approved security function, the algorithm
+implementation must meet all the requirements of FIPS 140-2 and must
+successfully complete the cryptographic algorithm validation process.
+
+Limitations
+-----------
+
+* Only NIST CAVP request files are parsed by this application.
+* The version of request file supported is ``CAVS 21.0``
+* If the header comment in a ``.req`` file does not contain a Algo tag
+  i.e ``AES,TDES,GCM`` you need to manually add it into the header comment for
+  example::
+
+      # VARIABLE KEY - KAT for CBC / # TDES VARIABLE KEY - KAT for CBC
+
+* The application does not supply the test vectors. The user is expected to
+  obtain the test vector files from `NIST
+  <https://csrc.nist.gov/projects/cryptographic-algorithm-validation-
+  program/block-ciphers>`_ website. To obtain the ``.req`` files you need to
+  email a person from the NIST website and pay for the ``.req`` files.
+  The ``.rsp`` files from the site can be used to validate and compare with
+  the ``.rsp`` files created by the FIPS application.
+
+* Supported test vectors
+    * AES-CBC (128,192,256) - GFSbox, KeySbox, MCT, MMT
+    * AES-GCM (128,192,256) - EncryptExtIV, Decrypt
+    * AES-CCM (128) - VADT, VNT, VPT, VTT, DVPT
+    * AES-CMAC (128) - Generate, Verify
+    * HMAC (SHA1, SHA224, SHA256, SHA384, SHA512)
+    * TDES-CBC (1 Key, 2 Keys, 3 Keys) - MMT, Monte, Permop, Subkey, Varkey,
+      VarText
+
+Application Information
+-----------------------
+
+If a ``.req`` is used as the input file after the application is finished
+running it will generate a response file or ``.rsp``. Differences between the
+two files are, the ``.req`` file has missing information for instance if doing
+encryption you will not have the cipher text and that will be generated in the
+response file. Also if doing decryption it will not have the plain text until it
+finished the work and in the response file it will be added onto the end of each
+operation.
+
+The application can be run with a ``.rsp`` file and what the outcome of that
+will be is it will add a extra line in the generated ``.rsp`` which should be
+the same as the ``.rsp`` used to run the application, this is useful for
+validating if the application has done the operation correctly.
+
+
+Compiling the Application
+-------------------------
+
+* Compile Application
+
+    .. code-block:: console
+
+         make -C examples/fips_validation
+
+*  Run ``dos2unix`` on the request files
+
+    .. code-block:: console
+
+         dos2unix AES/req/*
+         dos2unix AES_GCM/req/*
+         dos2unix CCM/req/*
+         dos2unix CMAC/req/*
+         dos2unix HMAC/req/*
+         dos2unix TDES/req/*
+
+Running the Application
+-----------------------
+
+The application requires a number of command line options:
+
+    .. code-block:: console
+
+         ./fips_validation [EAL options]
+         -- --req-file FILE_PATH/FOLDER_PATH
+         --rsp-file FILE_PATH/FOLDER_PATH
+         [--cryptodev DEVICE_NAME] [--cryptodev-id ID] [--path-is-folder]
+
+where,
+  * req-file: The path of the request file or folder, separated by
+    ``path-is-folder`` option.
+
+  * rsp-file: The path that the response file or folder is stored. separated by
+    ``path-is-folder`` option.
+
+  * cryptodev: The name of the target DPDK Crypto device to be validated.
+
+  * cryptodev-id: The id of the target DPDK Crypto device to be validated.
+
+  * path-is-folder: If presented the application expects req-file and rsp-file
+    are folder paths.
+
+
+To run the application in linuxapp environment to test one AES FIPS test data
+file for crypto_aesni_mb PMD, issue the command:
+
+.. code-block:: console
+
+    $ ./fips_validation --vdev crypto_aesni_mb --
+    --req-file /PATH/TO/REQUEST/FILE.req --rsp-file ./PATH/TO/RESPONSE/FILE.rsp
+    --cryptodev crypto_aesni_mb
+
+To run the application in linuxapp environment to test all AES-GCM FIPS test
+data files in one folder for crypto_aesni_gcm PMD, issue the command:
+
+.. code-block:: console
+
+    $ ./fips_validation --vdev crypto_aesni_gcm0 --
+    --req-file /PATH/TO/REQUEST/FILE/FOLDER/
+    --rsp-file ./PATH/TO/RESPONSE/FILE/FOLDER/
+    --cryptodev-id 0 --path-is-folder
