While some platforms (e.g. Cavium Octeontx) do this operation in hardware, other platforms use software. This patchset introduces an ethernet Rx event adapter that dequeues packets from ethernet devices and enqueues them to event devices. This patch is based on a previous RFC[2] and supercedes [3], the main difference being that this version implements a common abstraction for HW and SW based packet transfers. The adapter is designed to work with the EAL service core[4] for SW based packet transfers. An eventdev PMD callback is used to determine that SW based packet transfer service is required. The application can discover and configure the service with a core mask using rte_service APIs. The adapter can service multiple ethernet devices and queues. For SW based packet transfers each queue is configured with a servicing weight to control the relative frequency with which the adapter polls the queue, and the event fields to use when constructing packet events. The adapter has two modes for programming an event's flow ID: use a static per-queue user-specified value or use the RSS hash. A detailed description of the adapter is contained in the header's comments.

(if one is used by the adapter) v4: - Unit test fixes (Santosh Shukla) - Pass ethernet device pointer to eventdev callback functions instead of ethernet port ID.
