[dpdk-dev] Future Direction for rte_eth_stats_get()

Some of the stats were HW specific rather than generic stats that should be exposed through rte_eth_stats and were migrated to the xstats API. http://dpdk.org/ml/archives/dev/2015-June/019915.html. The naming was also not generic enough to cover some of the drivers and in some cases what was exposed was only a partial view of the relevant stats.
They were marked as deprecated to deter people from using them in the future, but haven't been removed from all the driver implementations yet. The Registers that remain undeprecated are those considered to be generic.
Which registers are you particularly interested in that have been deprecated? Can you elaborate on what you mean by " scenarios where a static view is expected "
Thanks in advance.
