[dpdk-dev] [PATCH 2/3] crypto/scheduler: improve slave configuration

[Fan Zhang]

Since the new device configuration API is updated, we can make use of
this feature to the crypto scheduler PMD to configure its slaves
automatically with the same configurations it got. As originally the
slaves have to be manually configured one by one, this patch should
help reducing the coding complexity.
