[dpdk-dev] [PATCH v2 2/9] test/crypto: fix wrong AAD setting

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

AAD should not point at IV for AES algorithms.
For AES-GCM, AAD will point at additional data in the mbuf.
For the other algorithms (such as 3DES CBC), AAD is not used.

Fixes: ffbe3be0d4b5 ("app/test: add libcrypto")
CC: stable@dpdk.org
