From: Pablo de Lara @ 2016-01-29 14:15 UTC (permalink / raw)
  To: dev

Added new SW PMD which makes use of the libsso SW library,
which provides wireless algorithms SNOW 3G UEA2 and UIA2
in software.

This PMD supports cipher-only, hash-only and chained operations
("cipher then hash" and "hash then cipher") of the following
algorithms:
- RTE_CRYPTO_SYM_CIPHER_SNOW3G_UEA2
- RTE_CRYPTO_SYM_HASH_SNOW3G_UIA2

The SNOW 3G hash and cipher algorithms, which are enabled
by this crypto PMD are implemented by Intel's libsso software
library. For library download and build instructions,
see the documentation included (doc/guides/cryptodevs/snow3g.rst)

+SNOW 3G Crypto Poll Mode Driver
+==============================
+
+The SNOW 3G PMD (**librte_pmd_snow3g**) provides poll mode crypto driver
+support for utilizing Intel Libsso library, which implements F8 and F9 functions
+for SNOW 3G UEA2 cipher and UIA2 hash algorithms.
+
+Features
+--------
+
+SNOW 3G PMD has support for:
+
+Cipher algorithm:
+
+* RTE_CRYPTO_SYM_CIPHER_SNOW3G_UEA2
+
+Hash algorithm:
+
+* RTE_CRYPTO_SYM_HASH_SNOW3G_UIA2
+
+Limitations
+-----------
+
+* Chained mbufs are not supported.
+
+Installation
+------------
+
+To build DPDK with the SNOW3G_PMD the user is required to get
+the export controlled libsso library, sending a request to
+`DPDKUser_software_access@intel.com`, and compile it
+on their user system before building DPDK:
+
+.. code-block:: console
+
+	make -f Makefile_snow3g
+
+The environmental variable LIBSSO_PATH must be exported with the path
+where you extracted and built the libsso library and finally set
+CONFIG_RTE_LIBRTE_SNOW3G=y in config/common_linuxapp.
