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.
Features
--------
* ZUC (EIA3) supported only if hash offset field is byte-aligned.
* ZUC (EEA3) supported only if cipher length, cipher offset fields are byte-aligned.
+
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>`_.
+
After downloading the library, the user needs to unpack and compile it
-on their system before building DPDK::
+on their system before building DPDK:
+
+.. code-block:: console
+
+ make
+ make install
+
+.. note::
+
+ Compilation of the Multi-Buffer library is broken when GCC < 5.0, if library <= v0.53.
+ If a lower GCC version than 5.0, the workaround proposed by the following link
+ should be used: `<https://github.com/intel/intel-ipsec-mb/issues/40>`_.
+
+As a reference, the following table shows a mapping between the past DPDK versions
+and the external crypto libraries supported by them:

+ 20.02+ Multi-buffer library 0.53

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).
-
-* 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
To use the PMD in an application, user must:
-* Call rte_eal_vdev_init("crypto_zuc") within the application.
+* Call rte_vdev_init("crypto_zuc") within the application.
-* Use --vdev="crypto_zuc" in the EAL options, which will call rte_eal_vdev_init() internally.
+* Use --vdev="crypto_zuc" in the EAL options, which will call rte_vdev_init() internally.
The following parameters (all optional) can be provided in the previous two calls:
.. code-block:: console
- ./l2fwd-crypto -c 40 -n 4 --vdev="crypto_zuc,socket_id=1,max_nb_sessions=128"
+ ./l2fwd-crypto -l 1 -n 4 --vdev="crypto_zuc,socket_id=0,max_nb_sessions=128" \
+ -- -p 1 --cdev SW --chain CIPHER_ONLY --cipher_algo "zuc-eea3"
