[dpdk-dev] [PATCH v4 5/8] app/crypto-perf: overwrite mbuf when verifying

Wed Oct 4 05:46:10 CEST 2017
When running the verify test, mbufs in the pool were
populated with the test vector loaded from a file.
To avoid limiting the number of operations to the pool size,
mbufs will be rewritten with the test vector, before
linking them to the crypto operations.
