Subject: app/crypto-perf: check minimum lcore number
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0bb32d94973987c82351edd6e6e1a4e53dfd83a6;p=dpdk.git

app/crypto-perf: check minimum lcore number

The crypto performance application requires at least
two cores: one master core that launches the other slaves
and one core acting as slave running the crypto device.

Fixes: f8be1786b1b8 ("app/crypto-perf: introduce performance test application")
