[dpdk-dev] [PATCH v2 4/9] crypto/openssl: fix AEAD parameters

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

When using AES-GCM with OpenSSL, cipher direction
and authentication operation were being set incorrectly,
as the PMD was looking at the cipher and authentication
transform, instead of the new AEAD.

Fixes: b79e4c00af0e ("cryptodev: use AES-GCM/CCM as AEAD algorithms")
Cc: stable@dpdk.org
