As a next step, I'm wondering if it would be possible to remove
this limitation. We could replace the tables in struct rte_eth_stats
by a pointer to an array allocated dynamically at pmd setup.
It would break the API, so it should be announced first. I'm thinking
of something like:
struct rte_eth_generic_stats {
uint64_t ipackets;
uint64_t opackets;
uint64_t ibytes;
uint64_t obytes;
uint64_t imissed;
uint64_t ierrors;
uint64_t oerrors;
uint64_t rx_nombuf
};
struct rte_eth_stats {
struct rte_eth_generic_stats port_stats;
struct rte_eth_generic_stats *queue_stats;
};
The queue_stats array would always be indexed by queue_id.
The xstats would continue to report the generic stats per-port and
per-queue.
About the mapping API, either we keep it as-is, or it could
become a driver-specific API.
Thomas, what do you think?
Regards,
Olivier
