Subject: [dpdk-dev] [PATCH v3] crypto/aesni_mb: support newer version library only
Date: Mon, 25 Mar 2019 13:58:35 +0000	[thread overview]
Message-ID: <20190325135835.5070-1-roy.fan.zhang@intel.com> (raw)
Message-ID: <20190325135835.VHOmHpueai63JzlEgIgxhO8rkVT6hy686CRooPZC9zo@z> (raw)
In-Reply-To: <20190304145735.25267-1-roy.fan.zhang@intel.com>

As stated in 19.02 deprecation notice, this patch updates the
aesni_mb PMD to remove the support of older Intel-ipsec-mb
library version eariler than 0.52.

Signed-off-by: Fan Zhang <roy.fan.zhang@intel.com>
