 ZUC Crypto Poll Mode Driver
 ===========================
 
-The ZUC PMD (**librte_pmd_zuc**) provides poll mode crypto driver
-support for utilizing Intel Libsso library, which implements F8 and F9 functions
-for ZUC EEA3 cipher and EIA3 hash algorithms.
+The ZUC PMD (**librte_pmd_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 F9 functions for ZUC EEA3 cipher and EIA3 hash algorithms.

@@ -27,42 +27,52 @@ Limitations
 * Chained mbufs are not supported.
 * ZUC (EIA3) supported only if hash offset field is byte-aligned.
 * ZUC (EEA3) supported only if cipher length, cipher offset fields are byte-aligned.
-* ZUC PMD cannot be built as a shared library, due to limitations in
-  in the underlying library.
 
 
 Installation
 ------------
 
-To build DPDK with the ZUC_PMD the user is required to download
-the export controlled ``libsso_zuc`` library, by requesting it from
-`<https://networkbuilders.intel.com/network-technologies/dpdk>`_.
-Once approval has been granted, the user needs to log in
-`<https://networkbuilders.intel.com/dpdklogin>`_
-and click on "ZUC Library" link, to download the library.
+To build DPDK with the ZUC_PMD the user is required to download the multi-buffer
+library from `here <https://github.com/01org/intel-ipsec-mb>`_
+and compile it on their user system before building DPDK.
+The latest version of the library supported by this PMD is v0.53, which
+can be downloaded from `<https://github.com/01org/intel-ipsec-mb/archive/v0.53.zip>`_.

 Initialization
 --------------
 
 In order to enable this virtual crypto PMD, user must:
 
-* Export the environmental variable LIBSSO_ZUC_PATH with the path where
-  the library was extracted (zuc folder).
-
-* Export the environmental variable LD_LIBRARY_PATH with the path
-  where the built libsso library is (LIBSSO_ZUC_PATH/build).
-
-* Build the LIBSSO_ZUC library (explained in Installation section).
+* Build the multi buffer library (explained in Installation section).
 
 * Build DPDK as follows:
 
 .. code-block:: console
 
-	make config T=x86_64-native-linuxapp-gcc
+	make config T=x86_64-native-linux-gcc
 	sed -i 's,\(CONFIG_RTE_LIBRTE_PMD_ZUC\)=n,\1=y,' build/.config
 	make
