> The OPDL (Ordered Packet Distribution Library) eventdev is a specific
> implementation of the eventdev API. It is particularly suited to packet
> processing workloads that have high throughput and low latency 
> requirements. All packets follow the same path through the device.
> The order which packets  follow is determinted by the order in which
> queues are set up. Packets are left on the ring until they are transmitted.
> As a result packets do not go out of order.
>

>   event/opdl: add the opdl pmd header and init helper function
>   event/opdl: add the opdl pmd main body and xstats helper function
