[dpdk-dev] [PATCH 2/2] event/dpaa: support event crypto adapter

[Akhil Goyal]

event dpaa device support both ethernet as well as
crypto queues to be attached to it. eth_rx_adapter
provide infrastructure to attach ethernet queues and
crypto_adapter provide support for crypto queues.

This patch add support for dpaa_eventdev to attach
dpaa_sec queues.
