[dpdk-dev] [PATCH] app/crypto-perf: check minimum lcore number

[Pablo de Lara]

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")
Cc: stable@dpdk.org
