Subject: [dpdk-dev] [PATCH] drivers/aesni_gcm: fix zero data operation
Date: Mon, 14 Aug 2017 01:45:21 +0100	[thread overview]
Message-ID: <20170814004521.75366-1-pablo.de.lara.guarch@intel.com> (raw)

When data length passed to the PMD was zero,
the PMD was trying to get more data from a non-existent
next segment.

Fixes: 9c2a5775c028 ("crypto/aesni_gcm: migrate from MB library to ISA-L")
Cc: stable@dpdk.org
