[v4,4/5] power: modify return of queue_stopped
Checks
Commit Message
Since some vdevs like virtio and vhost do not support rxq_info_get and
queue state inquiry, the error return value -ENOTSUP need to be ignored
when queue_stopped cannot get rx queue information and rx queue state.
This patch changes the return value of queue_stopped when
rte_eth_rx_queue_info_get return ENOTSUP to support vdevs which cannot
provide rx queue information and rx queue state enable power management.
