This patch series completes the removal (with help of AI) of the queue
stats counters an mapping. There are also a couple of uncovered bugs
in the process.
The per-queue stats mapping mechanism
(rte_eth_dev_set_{rx,tx}_queue_stats_mapping
and the queue_stats_mapping_set ethdev op) was a workaround for hardware that
could only expose a limited number of queue stat registers. It let an
application
fold many queues onto a small set of counters. Since 25.11 queue statistics are
filled in directly by the ethdev layer indexed by queue id, so the mapping is no
longer needed; the functions were deprecated then by commit 2863cbd9ee6d.
Tried to split out the bug fixes where possible.
The big patch is a tree wide removal of RTE_ETHDEV_QUEUE_STAT_CNTRS.
Instead the rte_ethdev allocates the temporary qstats array based
on what the driver reports as number of queues; before querying the
driver for its stats. The error counters are no longer per-queue
because that wasn't that helpful, instead error counters are global.
The same logic to map per-queue stats into xstats still exists and
the user visible xstats remain the same. The impact is only to the
driver API.
Also added test for statistics in pmd_ring test to make sure
there is test coverage.
