Konstantin Ananyev 8d7d4fcdca ethdev: change input parameters for Rx queue count
Currently majority of fast-path ethdev ops take pointers to internal
queue data structures as an input parameter.
While eth_rx_queue_count() takes a pointer to rte_eth_dev and queue
index.
For future work to hide rte_eth_devices[] and friends it would be
plausible to unify parameters list of all fast-path ethdev ops.
This patch changes eth_rx_queue_count() to accept pointer to internal
queue data as input parameter.
While this change is transparent to user, it still counts as an ABI change,
as eth_rx_queue_count_t is used by ethdev public inline function
rte_eth_rx_queue_count().
