[dpdk-dev] [PATCH v1 2/2] crypto/aesni_mb: improve security instance setup

[David Coyle]

This patch makes some minor improvements to the security instance setup
for the AESNI-MB PMD. All of this setup code is now in one '#ifdef
AESNI_MB_DOCSIS_SEC_ENABLED' block. Enabling the
RTE_CRYPTODEV_FF_SECURITY feature for the device is also moved to this
block.

Fixes: fda5216fba55 ("crypto/aesni_mb: support DOCSIS protocol")
