Detailed Description

Wireless base band device abstraction APIs.

This API allows an application to discover, configure and use a device to process operations. An asynchronous API (enqueue, followed by later dequeue) is used for processing operations.

The functions in this API are not thread-safe when called on the same target object (a device, or a queue on a device), with the exception that one thread can enqueue operations to a queue while another thread dequeues from the same queue.

op	The operation be performed for the vector.RTE_INTR_EVENT_ADD or RTE_INTR_EVENT_DEL.
data	User context, that will be returned in the epdata.data field of the rte_epoll_event structure filled in by rte_epoll_wait().
