[dpdk-dev] [PATCH 07/10] app/test: add aesni_mb security cpu crypto perftest

[Fan Zhang <roy.fan.zhang@intel.com>]

Since crypto perf application does not support rte_security, this patch
adds a simple AES-CBC-SHA1-HMAC CPU crypto performance test to crypto
unittest application. The test includes different key and data sizes test
with single buffer test items and will display the throughput as well as
cycle count performance information.
