[dpdk-dev] [PATCH v6 0/9] Expose IXGBE extended stats to DPDK apps

[Maryam Tahhan]

This patch set implements xstats_get() and xstats_reset() in dev_ops for
ixgbe to expose detailed error statistics to DPDK applications. The
dump_cfg application was extended to demonstrate the usage of
retrieving statistics for DPDK interfaces and renamed to proc_info
in order reflect this new functionality. This patch set also removes non
generic statistics from the statistics strings at the ethdev level and
marks the relevant registers as depricated in struct rte_eth_stats.

v2:
 - Fixed patch dependencies.
 - Broke down patches into smaller logical changes.

v3:
 - Removes non-generic stats fields in rte_stats_strings and deprecates
   the fields related to them in struct rte_eth_stats.
 - Modifies rte_eth_xstats_get() to return generic stats and extended
   stats.
 
v4:
 - Replace count use in the loop in ixgbe_dev_xstats_get() function
   definition with i.
 - Breakdown "ixgbe: add NIC specific stats removed from ethdev" into
   two patches, one that adds the stats and another that extends
   ierrors to include more error stats.
 - Remove second call to ixgbe_dev_xstats_get() from
   rte_eth_xstats_get().

v5:
 - Added documentation for proc_info.
 - Fixed proc_info copyright year.
 - Display queue stats for all devices in proc_info.

v6:
 - Modified the driver implementation of ixgbe_dev_xstats_get() so that
   it doesn't worry about the generic stats written by the generic layer.
