> In mlx5 PMD, MLX5_IPOOL_JUMP ipool configuration is used to initialize the
> ipool containing either:
> 
> - flow table entry when DV flow engine is chosen or,
> - group table entry when HW steering flow engine is chosen.
> 
> Default configuration for MLX5_IPOOL_JUMP ipool specified entry size as size
> of mlx5_flow_tbl_data_entry struct, used with DV flow engine.
> This could lead to memory corruption when mlx5_flow_group struct (used
> with HW steering flow engine) would have bigger size than
> mlx5_flow_tbl_data_entry.
> 
> This patch fixes that. Entry size for MLX5_IPOOL_JUMP ipool is chosen
> dynamically based on device configuration.
