[dpdk-dev] [PATCH 5/5] crypto/dpaa_sec: add support for AES CMAC integrity check

[Hemant Agrawal <hemant.agrawal@nxp.com>]

From: Gagandeep Singh <g.singh@nxp.com>

This patch adds support for AES_CMAC integrity in non-security mode.
This patch modifies the camm flib to handles the AES CMAC
without conflicting the proto ALG operations. i.e. by creating
another ALG operation routine.
