[dpdk-dev] [PATCH] test/crypto-perf: fix crash issue with asym perf test

[<kirankumark@marvell.com>]

From: Kiran Kumar K <kirankumark@marvell.com>

While populating the crypto ops in case of asymmetric, result
is being allocated from stack. This is causing crash in the
application. And operation type is also not being initialized
properly. Adding a fix by allocating the result from global
memory and initialized the operation memory properly.

Fixes: ba588ce3f9339 ("test/crypto-perf: test asymmetric crypto throughput")
