  This patchset adds support to the QAT PMD for combined cipher-crc
processing for DOCSIS on the QAT device. The current QAT PMD
implementation of cipher-crc calculates CRC in software and uses QAT
for encryption/decryption offload.

Note: The previous code-path is still retained for QAT firmware
versions without support for combined cipher-crc offload.

- Support has been added to DPDK QAT PMD to enable the use of the
cipher-crc offload feature on gen2/gen3/gen4 QAT devices.

- A cipher-crc offload capability check has been added to the queue
pair setup function to determine if the feature is supported on the
QAT device.

v1:
* initial version

v2:
* fixed centos compilation error for missing braces around
  initializer

v3:
* updated the file qat.rst with details of new configuration

v4:
* updated v23.07 release note
* moved cipher crc capability check test vectors to top of
  qat_qp.c and made the vectors static const
* changed log string to be all on one line in qat_device.c
* changed word parameter to devargs in qat.rst
