> Subject: [dpdk-dev] [PATCH] net/mlx5: fix xcapsulation validation
>
> The encapsulation and decapsulation actions are divided into 2 types:
> L2 and L3.
> In order to configure L3 xcapsulation actions the user should use both
> RAW_DECAP and RAW_ENCAP and setting the appropriated data sizes in
> their action configuration structures.
>
> The PMD flow validation wrongly didn't detect the RAW_DECAP
> and RAW_ENCAP combination to distinguish between L3_DECAP and
> L3_ENCAP.
> Thus, some xcapsulation related validation failed.
> For example, when configuring modify header action before L3_DECAP.
>
> Simplify the xcapsulation defines and fix the L3 xcapsulation detection
> using the action configuration data sizes.
>
> By the way, add the hairpin validation in this area.
>
> Fixes: d85c7b5ea59f ("net/mlx5: split hairpin flows")
> Fixes: 8ba9eee4ce32 ("net/mlx5: add raw data encap/decap to Direct Verbs")
