> Subject: [PATCH] net/mlx5: fix validation of drop action
> 
> Function mlx5_flow_validate_action_drop() checks if another fate action is
> already present in this flow rule, using defined value
> MLX5_FLOW_FATE_ACTIONS.
> This patch enhances the check using value (MLX5_FLOW_FATE_ACTIONS |
> MLX5_FLOW_FATE_ESWITCH_ACTIONS) to make sure all relevant fate
> actions are checked.
