[dpdk-dev] [PATCH v2 3/8] event/opdl: add the opdl pmd main body and xstats helper function
Liang Ma

Fri Dec 15 12:26:24 CET 2017
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
This commit only adds the implementation, no existing DPDK files
are modified.
