[dpdk-dev] About RTE_MAX_ETHPORT_QUEUE_STATS_MAPS

[Alejandro Lucero]

Hi,

Documentation and header files describe stat_idx parameter for

rte_eth_dev_set_tx_queue_stats_mapping

and

rte_eth_dev_set_rx_queue_stats_mapping

as

The value must be in the range
[0, RTE_MAX_ETHPORT_QUEUE_STATS_MAPS - 1]

I have not found a definition for RTE_MAX_ETHPORT_QUEUE_STATS_MAPS but the
per queue counters inside struct rte_eth_stats are arrays with length
RTE_ETHDEV_QUEUE_STAT_CNTRS which is defined at

config/defconfig_x86_64-default-linuxapp-gcc

CONFIG_RTE_ETHDEV_QUEUE_STAT_CNTRS=16

I assume RTE_MAX_ETHPORT_QUEUE_STATS_MAPS is equal to
CONFIG_RTE_ETHDEV_QUEUE_STAT_CNTRS.

Can anyone confirm this?

Thanks
