Subject: [dpdk-dev] [PATCH v5 02/15] crypto: add total raw buffer length
Date: Sun, 17 Oct 2021 21:46:38 +0530 [thread overview]
Message-ID: <20211017161651.9220-3-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20211017161651.9220-1-hemant.agrawal@nxp.com>
From: Gagandeep Singh <g.singh@nxp.com>
The current crypto raw data vectors is extended to support
rte_security usecases, where we need total data length to know
how much additional memory space is available in buffer other
than data length so that driver/HW can write expanded size
data after encryption.
