Subject[PATCH net-next] xsk: Return -EINVAL instead of -EBUSY after xsk_get_pool_from_qid() fails
Date
xsk_get_pool_from_qid() fails not because the device's queues are busy,
but because the queue_id exceeds the current number of queues.
So when it fails, it is better to return -EINVAL instead of -EBUSY.
