> For specific use-cases, a port can be used for Tx only.
> In such case, number of Rx queues can be set to 0 to save resources, hence

> It also includes update of validation functions for relevant actions,
> mlx5_flow_validate_action_queue() and mlx5_flow_validate_action_rss(),
> to prevent creation of flow rules with these actions when number of Rx
> queues is 0.
