> Subject: [PATCH 5/5] net/mlx5: fix GRE protocol type translation
> 
> When application creates several flows to match on GRE tunnel without
> explicitly specifying GRE protocol type value in flow rules, PMD will translate
> that to zero mask.
> RDMA-CORE cannot distinguish between different inner flow types and
> produces identical matchers for each zero mask.
> 
> The patch extracts inner header type from flow rule and forces it in GRE
> protocol type, if application did not specify any without explicitly specifying
> GRE protocol type value in flow rules, protocol type value.
