inlinestatic

Send fifo io event to vpp worker thread.

Because there may be multiple writers to one of vpp's queues, this protects message allocation and enqueueing.

Parameters

mq	vpp message queue
f	fifo for which the event is sent
evt_type	type of event
noblock	flag to indicate is request is blocking or not

Returns: 0 if success, negative integer otherwise
