The AES-NI MB PMD has current only been tested on Fedora 21 64-bit with gcc.
+The AES-NI MB PMD supports synchronous mode of operation with
+``rte_cryptodev_sym_cpu_crypto_process`` function call.

Limitations
-----------
* Chained mbufs are not supported.
-* RTE_CRYPTO_AEAD_AES_GCM only works properly when the multi-buffer library is
- 0.51.0 or newer.
-* RTE_CRYPTO_HASH_AES_GMAC is supported by library version v0.51 or later.
-* RTE_CRYPTO_HASH_SHA* is supported by library version v0.52 or later.
+* Out-of-place is not supported for combined Crypto-CRC DOCSIS security
+ protocol.
+* RTE_CRYPTO_CIPHER_DES_DOCSISBPI is not supported for combined Crypto-CRC
+ DOCSIS security protocol.
Installation
To build DPDK with the AESNI_MB_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 v0.52, which
-can be downloaded from `<https://github.com/01org/intel-ipsec-mb/archive/v0.52.zip>`.
+The latest version of the library supported by this PMD is v0.54, which
+can be downloaded from `<https://github.com/01org/intel-ipsec-mb/archive/v0.54.zip>`_.
+
+.. code-block:: console
+
+ make
+ make install
+
+The library requires NASM to be built. Depending on the library version, it might
+require a minimum NASM version (e.g. v0.54 requires at least NASM 2.14).
+
+NASM is packaged for different OS. However, on some OS the version is too old,
+so a manual installation is required. In that case, NASM can be downloaded from
+`NASM website <https://www.nasm.us/pub/nasm/releasebuilds/?C=M;O=D>`_.
+Once it is downloaded, extract it and follow these steps:
.. code-block:: console
+ ./configure
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 Multi-Buffer library version supported by them:
17.05 - 17.08 0.45 - 0.48
17.11 0.47 - 0.48
18.02 0.48
- 18.05+ 0.49+
+ 18.05 - 19.02 0.49 - 0.52
+ 19.05 - 19.08 0.52
+ 19.11+ 0.52 - 0.54
============== ============================
For AES Counter mode (AES-CTR), the library supports two different sizes for Initialization
Vector (IV):
-* 12 bytes: used mainly for IPSec, as it requires 12 bytes from the user, which internally
+* 12 bytes: used mainly for IPsec, as it requires 12 bytes from the user, which internally
are appended the counter block (4 bytes), which is set to 1 for the first block
(no padding required from the user)
