[dpdk-dev] [PATCH v4 6/8] app/crypto-perf: do not populate the mbufs at init

Wed Oct 4 05:46:11 CEST 2017


For throughput and latency tests, it is not required
to populate the mbufs with any test vector.
For verify test, there is already a function that rewrites
the mbufs every time they are going to be used with
crypto operations.
