> - 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

> This could lead to memory corruption when mlx5_flow_group struct (used

> This patch fixes that. Entry size for MLX5_IPOOL_JUMP ipool is chosen
