8b35ad02db event/opdl: fix icc build
ICC reports the issue at compile time as follows.
error #592: variable "i" is used before its value is set
        RTE_SET_USED(i);

The patch is to fix it. GCC and CLANG has been tested as well.

d548ef513c event/opdl: add unit tests
This commit adds unit test inside the OPDL PMD. There is a PMd parameter
"self_test" can be used to triger the test when vdev bus probe opdl device

  e.g.

  sudo ./app/test --vdev="event_opdl0,self_test=1"

3c7f3dcfb0 event/opdl: add PMD main body and helper function
This commit adds a OPDL implementation of the eventdev API. The
implementation here is intended to enable the community to use
the OPDL infrastructure under eventdev API.

The main components of the implementation is three files:
  - opdl_evdev.c              Creation, configuration, etc
  - opdl_evdev_xstats.c       helper function to support stats collection
  - opdl_evdev.h              include the main data structure of opdl
                              device and all the function prototype
                              need to be exposed to support eventdev API.

  - opdl_evdev_init.c         implement all initailization helper function

This commit only adds the implementation, no existing DPDK files
are modified.

4236ce9bf5 event/opdl: add OPDL ring infrastructure library
OPDL ring is the core infrastructure of OPDL PMD. OPDL ring library
provide the core data structure and core helper function set. The Ring
implements a single ring multi-port/stage pipelined packet distribution
mechanism. This mechanism has the following characteristics:

• No multiple queue cost, therefore, latency is significant reduced.
• Fixed dependencies between queue/ports is more suitable for complex.
  fixed pipelines of stateless packet processing (static pipeline).
• Has decentralized distribution (no scheduling core).
• Packets remain in order (no reorder core(s)).
* Update build system to enable compilation.
