Currently, the queue stats mapping has the following problems:
1) Many PMD drivers don't support queue stats mapping. But there is no
failure message after executing the command "set stat_qmap rx 0 2 2".
2) Once queue mapping is set, unrelated and unmapped queues are also
displayed.
3) The configuration result does not take effect or can not be queried
in real time.
4) The mapping arrays, "tx_queue_stats_mappings_array" &
"rx_queue_stats_mappings_array" are global and their sizes are based
on fixed max port and queue size assumptions.
5) These record structures, 'map_port_queue_stats_mapping_registers()'
and its sub functions are redundant for majority of drivers.
6) The display of the queue stats and queue stats mapping is mixed
together.
Since xstats is used to obtain queue statistics, we have made the
following simplifications and adjustments:
1) If PMD requires and supports queue stats mapping, configure to driver
in real time by calling ethdev API after executing the command "set
stat_qmap rx/tx ...". If not, the command can not be accepted.
2) Based on the above adjustments, these record structures,
'map_port_queue_stats_mapping_registers()' and its sub functions can
be removed. "tx-queue-stats-mapping" & "rx-queue-stats-mapping"
parameters, and 'parse_queue_stats_mapping_config()' can be removed
too.
3) remove display of queue stats mapping in 'fwd_stats_display()' &
'nic_stats_display()', and obtain queue stats by xstats. Since the
record structures are removed, 'nic_stats_mapping_display()' can be
deleted.
