[dpdk-dev] [PATCH 3/3] crypto/snow3g: use IPSec library

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

Link against Intel IPSec Multi-buffer library, which
added support for SNOW3G-UEA2 and SNOW3G-UIA2 from version v0.53,
moving from libSSO SNOW3G library.

 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.
+The SNOW3G PMD (**librte_snow3g_zuc**) provides poll mode crypto driver support for
+utilizing `Intel IPSec Multi-buffer library <https://github.com/01org/intel-ipsec-mb>`_
+which implements F8 and F8 functions for SNOW 3G UEA2 cipher and UIA2 hash algorithms.

-**Note**: When encrypting with SNOW3G UEA2, by default the library
-encrypts blocks of 4 bytes, regardless the number of bytes to
-be encrypted provided (which leads to a possible buffer overflow).
-To avoid this situation, it is necessary not to pass
-3GPP_SAFE_BUFFERS as a compilation flag.
-For this, in the Makefile of the library, make sure that this flag
