> Subject: [PATCH v2 6/6] net/mlx5: not split hairpin flow in explicit mode
> 
> In the current implementation, the hairpin flow will be split into two flows
> implicitly if there is some action that only belongs to the TX part. A TX device
> flow will be inserted by the mlx5 PMD itself.
> 
> In hairpin between two ports, the explicit TX flow mode will be the only one to
> be supported. It is not the appropriate behavior to insert a TX flow into
> another device implicitly. The application could create any flow as it likes and
> has full control of the user flows. Hairpin flows will have no difference from
> standard flows and the application can decide how to chain RX and TX flows
> together.
> 
> Even in the single port hairpin, this explicit TX flow mode could also be
> supported.
> 
> When checking if the hairpin needs to be split, just return if the hairpin queue
> is with "tx_explicit" attribute. Then in the following steps for validation and
> translation, the code path will be the same as that for standard flows.
