Subject: [dpdk-dev] [RFC 05/16] crypto/dpaa2_sec: support raw datapath APIs
Date: Thu, 12 Aug 2021 12:42:33 +0530
Message-ID: <20210812071244.28799-6-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20210812071244.28799-1-hemant.agrawal@nxp.com>

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

This path add framework for raw API support.
The initial patch only test cipher only part.
