What is the expected behavior if queues configured with
RTE_EVENT_QUEUE_CFG_SINGLE_LINK attempted to link by multiple ports?
Based on the head-file, the expected behavior is following,
(-EDQUOT) Quota exceeded(Application tried to link the queue
configured with RTE_EVENT_QUEUE_CFG_SINGLE_LINK to more than one event ports)
