> +* 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.
