> Different with SW steering implementation, take advantage of HW steering
> bulk action allocation support, in HW steering only one single CT pool is
> needed.
> 
> An indexed pool is introduced to record allocated actions from bulk and CT
> action state etc. Once one CT action is allocated from bulk, one indexed
> object will also be allocated from the indexed pool, similar for deallocate.
> That makes mlx5_aso_ct_action can also be managed by that indexed pool, no
> need to be reserved from mlx5_aso_ct_pool. The single CT pool is also saved
> to mlx5_aso_ct_action struct directly.
> 
> The ASO operation functions are shared with SW steering implementation.
