+AESN-NI Multi Buffer Crytpo Poll Mode Driver
+============================================
+
+
+The AESNI MB PMD (**librte_pmd_aesni_mb**) provides poll mode crypto driver
+support for utilising Intel multi buffer library, see the white paper
+`Fast Multi-buffer IPsec Implementations on Intel® Architecture Processors
+<https://www-ssl.intel.com/content/www/us/en/intelligent-systems/intel-technology/fast-multi-buffer-ipsec-implementations-ia-processors-paper.html?wapkw=multi+buffer>`_.
+
+The AES-NI MB PMD has current only been tested on Fedora 21 64-bit with gcc.
+
+Features
+--------
+
+AESNI MB PMD has support for:
+
+Cipher algorithms:
+
+* RTE_CRYPTO_SYM_CIPHER_AES128_CBC
+* RTE_CRYPTO_SYM_CIPHER_AES256_CBC
+* RTE_CRYPTO_SYM_CIPHER_AES512_CBC
+
+Hash algorithms:
+
+* RTE_CRYPTO_SYM_HASH_SHA1_HMAC
+* RTE_CRYPTO_SYM_HASH_SHA256_HMAC
+* RTE_CRYPTO_SYM_HASH_SHA512_HMAC
+
+Limitations
+-----------
+
+* Chained mbufs are not supported.
+* Hash only is not supported.
+* Cipher only is not supported.
+* Only in-place is currently supported (destination address is the same as source address).
+* Only supports session-oriented API implementation (session-less APIs are not supported).
+* Not performance tuned.
+
+Installation
+------------
+
+To build DPKD with the AESNI_MB_PMD the user is required to download the library
+from `here <https://downloadcenter.intel.com/download/22972>`_ and compile it on
+their user system before building DPDK. The environmental variable
+AESNI_MULTI_BUFFER_LIB_PATH must be exported with the path where you extracted
+and built the multi buffer library and finally set
+CONFIG_RTE_LIBRTE_PMD_AESNI_MB=y in config/common_linuxapp.
