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.

Flags to indicate the reason why a previous enqueue may not have consumed all requested operations. In case of multiple reasons the latter supersedes a previous one.
