os_mqueue_init() function

Initializes an mqueue. An mqueue is a queue of mbufs that ties to a particular task's event queue. Mqueues form a helper API around a common paradigm: wait on an event queue until at least one packet is available, then process a queue of packets. When mbufs are available on the queue, an event OS_EVENT_T_MQUEUE_DATA will be posted to the task's mbuf queue.
