Example applications are also not close to real work application. But they should
Have end to end functionality available with some missing processing in between.
I would say:
- modifying l2fwd-crypto can be preference 1
- moving multiprocess crypto to test app can be preference 2 as it is just a unit test application for multi process.
- moving to examples/multi-process will be preference 3.
