> +* ethdev: Split the ``struct eth_dev_ops`` struct to hide it as much as possible
> +  will be done in 20.11.
> +  Currently the ``struct eth_dev_ops`` struct is accessible by the application
> +  because some inline functions, like ``rte_eth_tx_descriptor_status()``,
> +  access the struct directly.
> +  The struct will be separate in two, the ops used by inline functions will be moved
> +  next to Rx/Tx burst functions, rest of the ``struct eth_dev_ops`` struct will be
> +  moved to header file for drivers to hide it from applications.
