Subject: app/crypto-perf: do not populate the mbufs at init
X-Git-Tag: spdx-start~1411
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=8e4b860141a1f794aafa0494939d2df223bf43b6

app/crypto-perf: do not populate the mbufs at init

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.
