Subject: [EXT] [PATCH v4] ethdev: support congestion management
External Email
----------------------------------------------------------------------
From: Jerin Jacob <jer...@marvell.com>
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.
