This issue happens when device stop (rte_eth_dev_stop()) will be called after device start (rte_eth_dev_start()) without any incoming packets received since device start. In this case both rxq->rx_tail and rxq->rxrearm_start equal to 0 and release cycle will not be executed. On the next device start (rte_eth_dev_start()) new set of mbufs for the RX queue will be allocated.
