[dpdk-dev] [PATCH] test_cryptodev_perf: IV and digest should be stored at a DMAeble address

[<akhil.goyal@nxp.com>]

From: Akhil Goyal <akhil.goyal@nxp.com>

For physical crypto devices, IV and digest are processed by the crypto
device which need the contents to be written on some DMA able address.

So in order to do that, IV and digest are accomodated in the packet.
