Subject: [dpdk-dev] [PATCH v3 04/15] crypto: fix raw process for multi-seg case
Date: Wed, 13 Oct 2021 23:57:09 +0530	[thread overview]
Message-ID: <20211013182720.32486-5-hemant.agrawal@nxp.com> (raw)
In-Reply-To: <20211013182720.32486-1-hemant.agrawal@nxp.com>

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

If no next segment available the “for” loop will fail and it still
returns i+1 i.e. 2, which is wrong as it has filled only 1 buffer.
