[PATCH v4 4/6] aesni_mb_pmd: Initial implementation of multi buffer based crypto device

[Declan Doherty <declan.doherty@intel.com>]

This patch provides the initial implementation of the AES-NI multi-buffer
based crypto poll mode driver using DPDK's new cryptodev framework.

This PMD is dependent on Intel's multibuffer library, see the whitepaper
"Fast Multi-buffer IPsec Implementations on Intel® Architecture
Processors", see ref 1 for details on the library's design and ref 2 to
download the library itself. This initial implementation is limited to
supporting the chained operations of "hash then cipher" or "cipher then
hash" for the following cipher and hash algorithms:

Cipher algorithms:
  - RTE_CRYPTO_CIPHER_AES128_CBC
  - RTE_CRYPTO_CIPHER_AES256_CBC
  - RTE_CRYPTO_CIPHER_AES512_CBC

Hash algorithms:
  - RTE_CRYPTO_AUTH_SHA1_HMAC
  - RTE_CRYPTO_AUTH_SHA256_HMAC
  - RTE_CRYPTO_AUTH_SHA512_HMAC
  - RTE_CRYPTO_AUTH_AES_XCBC_MAC

Important Note:
Due to the fact that the multi-buffer library is designed for
accelerating IPsec crypto oepration, the digest's generated for the HMAC
functions are truncated to lengths specified by IPsec RFC's, ie RFC2404
for using HMAC-SHA-1 with IPsec specifies that the digest is truncate
from 20 to 12 bytes.

Build instructions:
To build DPKD with the AESNI_MB_PMD the user is required to download
(ref 2) and compile the multi-buffer library on there 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.

Current status: It's doesn't support crypto operation
across chained mbufs, or cipher only or hash only operations.

+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.
