 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 v0.53, which
-can be downloaded from `<https://github.com/01org/intel-ipsec-mb/archive/v0.53.zip>`.
+The latest version of the library supported by this PMD is v0.54, which

+
+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>`_.
