[dpdk-dev] [PATCH v2 00/31] crypto/qat: refactor to support multiple

[Fiona Trahe <fiona.trahe@intel.com>]

Note this patchset is targeting 18.08 release

The QAT crypto PMD was peppered with references to rte_cryptodev
artefacts.
Also the pci device it presented to the API layer was
entirely owned by the one cryptodev device instance created by the
probe.
This patchset refactors the PMD so one pci device can present out
multiple different device instances to implement different APIs,
specifically cryptodev and compressdev instances.
The code is refactored into
 - common code which handles the pci device discovery, configuration,
   queue-pair setup, stats gathering and data-path enqueue and dequeue.
 - service-specific code for symmetric crypto, which is a thin layer
   implementing the cryptodev API and using the common code.
 - place-holder files for service-specific code to support asymmetric
   crypto and compression services in future.
The code is all still in the crypto/qat directory as it is functionally
unchanged, still only supporting a symmetric crypto service. The
code will move to drivers/common, /crypto and /compress in
a future patch when this is needed for a compression PMD.


Changes for v2:
 - fixed some bugs compiled in when debug enabled
 - added patch to remove MAX_NB_SESSIONS from config file
 - removed SPDX license patch as already applied
 - documented device name formats
