Subject: [dpdk-dev] [PATCH v4 6/8] examples/ipsec-secgw: cpu crypto support
Date: Tue, 28 Jan 2020 04:16:40 +0100
Message-ID: <20200128031642.15256-7-marcinx.smoczynski@intel.com> (raw)
In-Reply-To: <20200128031642.15256-1-marcinx.smoczynski@intel.com>

Add support for CPU accelerated crypto. 'cpu-crypto' SA type has
been introduced in configuration allowing to use abovementioned
acceleration.

Legacy mode is not currently supported.
