Subject: [dpdk-dev] [PATCH v4 10/12] cryptodev: add user data size to symmetric session
Date: Wed,  9 Jan 2019 22:56:07 +0000	[thread overview]
Message-ID: <20190109225609.20590-11-roy.fan.zhang@intel.com> (raw)
In-Reply-To: <20190109225609.20590-1-roy.fan.zhang@intel.com>

This patch adds a user_data_sz field to cryptodev symmetric session.
The field is used to check if reading or writing the session's user
data field is eligible.
