[dpdk-dev] [PATCH v3 6/8] app/eventdev: add event Rx adapter setup

[Pavan Nikhilesh]

Add functions to setup and configure Rx adapter based on the number of
ethdev ports setup.

Signed-off-by: Pavan Nikhilesh <pbhagavatula at caviumnetworks.com>
Acked-by: Jerin Jacob <jerin.jacob at caviumnetworks.com>

 v3 Changes:
  - Fix compilation issues for gcc version < 5

 v2 Changes:
  - Used default eventdev config values instead of hardcoded values.
