Please take care of two more things.
1) In mlx5_rx_intr_disable(),
mlx5_rxq_ibv_get() isn't paired with mlx5_rxq_ibv_release()
This would need a separate patch.
2) In mlx5_rx_intr_vec_disable()
Please fix the comment having the old name - priv_rx_intr_vec_enable().
This should be mlx5_rx_intr_vec_enable()
No need to have a separate patch. You can fix it in this patch.
With the change,
