Wireless algorithms like Snow3G needs input in bits. In this patch, changes have been made to incorporate this requirement in both QAT and SW PMD. Signed-off-by: Deepak Kumar Jain <deepak.k.jain@intel.com> Acked-by: Pablo de Lara <pablo.de.lara.guarch@intel.com>

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
|
|
|
|
Authentication algorithm:
|
|
|
|
* RTE_CRYPTO_SYM_AUTH_SNOW3G_UIA2
|
|
|
|
Limitations
|
|
-----------
|
|
|
|
* Chained mbufs are not supported.
|
|
* Snow3g(UEA2) supported only if cipher length, cipher offset fields are byte-aligned.
|
|
* Snow3g(UIA2) supported only if hash length, hash offset fields are byte-aligned.
|
|
|
|
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_PMD_SNOW3G=y in config/common_base.
