>
> NIC HW controllers often come with congestion management support on
> various HW objects such as Rx queue depth or mempool queue depth.
>
> Also, it can support various modes of operation such as RED (Random early
> discard), WRED etc on those HW objects.
>
> Add a framework to express such modes(enum rte_cman_mode) and
> introduce (enum rte_eth_cman_obj) to enumerate the different objects
> where the modes can operate on.
>
> Add RTE_CMAN_RED mode of operation and
> RTE_ETH_CMAN_OBJ_RX_QUEUE,
> RTE_ETH_CMAN_OBJ_RX_QUEUE_MEMPOOL objects.
>
> Introduce reserved fields in configuration structure backed by
> rte_eth_cman_config_init() to add new configuration parameters without
> ABI breakage.
>
> Add rte_eth_cman_info_get() API to get the information such as supported
> modes and objects.
>
> Add rte_eth_cman_config_init(), rte_eth_cman_config_set() APIs to
> configure congestion management on those object with associated mode.
>
> Finally, add rte_eth_cman_config_get() API to retrieve the applied
> configuration.
