Crypto API and device framework

This series of patches defines a set of application burst oriented APIs for asynchronous symmetric cryptographic functions within DPDK. It also contains a poll mode driver cryptographic device framework for the implementation of crypto devices within DPDK.

In the patch set we also have included 2 reference implementations of crypto PMDs. Currently both implementations support AES-CBC with HMAC_SHA1/SHA256/SHA512 authentication operations. The first device is a purely software PMD based on Intel's multi-buffer library, which utilises both AES-NI instructions and vector operations to accelerate crypto operations and the second PMD utilises Intel's Quick Assist Technology (on DH895xxC) to provide hardware accelerated crypto operations.

The API set supports two functional modes of operation:

1, A session oriented mode. In this mode the user creates a crypto session which defines all the immutable data required to perform a particular crypto operation in advance, including cipher/hash algorithms and operations to be performed as well as the keys to used etc. The session is then referenced by the crypto operation data structure which is a data structure specific to each mbuf. It is contains all mutable data about the crypto operation to be performed, such as data offsets and lengths into the mbuf's data payload for cipher and hash operations to be performed.

2, A session-less mode. In this mode the user is able to provision crypto operations on an mbuf without the need to have a cached session created in advance, but at the cost of entailing the overhead of calculating authentication pre-computes and preforming key expansions in-line with the crypto operation. The crypto xform chain is directly attached to the op struct in this mode, so the op struct now contains all of the immutable crypto operation parameters that would be normally set within a session. Once all mutable and immutable parameters are set the crypto operation data structure can be attached to the specified mbuf and enqueued on a specified crypto device for processing.

The patch set contains the following features:
- Crypto device APIs and device framework
- Implementation of a software crypto PMD based on multi-buffer library
- Implementation of a hardware crypto PMD baed on Intel QAT(DH895xxC)
- Unit and performance test's which give and example of utilising the crypto API's.
- Sample application which performs crypto operations on the IP payload of the packets being forwarded

Current Status:
There is no support for chained mbuf's and as mentioned above the PMD's have currently implemented support for AES128-CBC/AES192-CBC/AES256-CBC and HMAC_SHA1/SHA256/SHA512 and AES_XCBC_MAC.

v8:
- Doxygen comment fix for rte_pktmbuf_mtophys macro
- Doxygen fixes for public headers in rte_crypto.h
- QAT documentation tidy up based on J. McNamara comments
- Detailed requirement to set YASM path when building multi-buffer library
- l2fwd-crypto: fix for 32-bit build; fix for possible memory leak if rte_cryptodev_burst_enqueue fails; and handling for failure to allocate rte_mbuf_offload.

v7:
- Fix typos in commit message of eal: add __rte_packed /__rte_aligned macros patch
- Include rte_mbuf_offload in doxygen build and updates file comments to clarify lib, usage. Also moved clean which was in wrong patch into this rte_mbuf_offload patch.
- Tidy up map file for cryptodev library.
- Add l2fwdc-crypto to main examples makefile.
v6:
- Fix 32-bit build issue caused by casting in new rte_pktmbuf_mtophys_offset macro
- Fix truncation of log message by new rte_pmd_debug_trace inline function

v5:
- Making ethdev marcos for function pointer and port id checking public and available for use in by the cryptodev. The intialise to patches combine changes from original cryptodev patch and discussion in
http://dpdk.org/ml/archives/dev/2015-November/027871.html
- Split out changes to create new __rte_packed and __rte_aligned macros into seperate patches form the main cryptodev patch set for clairty
- further code cleaning, removal of currently unsupported gcm code from aesni_mb pmd

v4:
- Some more EOF whitespace and checkpatch fixes

v3:
- Fixes a document build error, which I missed in the V2
- Fixes for remaining checkpatch errors
- Disables QAT and AESNI_MB PMD being build by default as they have external library dependences

v2:
- Introduces a new library to support attaching offload operations to a mbuf
- Remove unused APIs from cryptodev
- PMD code refactor due to new rte_mbuf_offload structure
- General bug fixes and code tidy up

Declan Doherty (10):

ethdev: make error checking macros public
eal: add __rte_packed /__rte_aligned macros
mbuf: add new marcos to get the physical address of data
cryptodev: Initial DPDK Crypto APIs and device framework release
mbuf_offload: library to support attaching offloads to a mbuf
qat_crypto_pmd: Addition of a new QAT DPDK PMD.
aesni_mb_pmd: Initial implementation of multi buffer based crypto
device
app/test: add cryptodev unit and performance tests
l2fwd-crypto: crypto
