Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable

Subject: [PATCH] crypto/openssl: fix extra bytes written at end of data

[ upstream commit 6b283a03216e120a697a0006341b3ab633e6a82c ]

Extra bytes are being written at end of data while process standard
openssl cipher encryption. This behaviour is unexpected.

This patch disable the padding feature in openssl library, which is
causing the problem.

Fixes: d61f70b4c918 ("crypto/libcrypto: add driver for OpenSSL library")
