When you say that DPDK and Crypto should run on separate cores,
would you still be using cryptodev (which is part of DPDK) or a different library?
Assuming the first option, you can build a pipeline where you have a separate
core receiving traffic, then enqueue this traffic to another core running
a crypto device and then dequeue the operations with another core.

If you have a single core processing the incoming packets, then you can use
the cryptodev multi-core scheduler to use several cores performing the
crypto workload on a same flow.
If you have several flows, then you could initialize multiple virtual devices,
used by multiple cores.
