[dpdk-dev] [PATCH v6 3/8] security: add cpu crypto action type

[Marcin Smoczynski]

Introduce CPU crypto action type allowing to differentiate between
regular async 'none security' and synchronous, CPU crypto accelerated
sessions.

This mode is similar to ACTION_TYPE_NONE but crypto processing is
performed synchronously on a CPU.
