[dpdk-dev] [PATCH v4 0/3] Extended xstats API in ethdev library to allow grouping of stats

[Jacek Piasecki]

Extended xstats API in ethdev library to allow grouping of stats logically
so they can be retrieved per logical grouping  managed by the application.
Changed existing functions rte_eth_xstats_get_names and rte_eth_xstats_get
to use a new list of arguments: array of ids and array of values.
ABI versioning mechanism was used to support backward compatibility.
Introduced two new functions rte_eth_xstats_get_all and
rte_eth_xstats_get_names_all which keeps functionality of the previous
ones (respectively rte_eth_xstats_get and rte_eth_xstats_get_names)
but use new API inside. Both functions marked as deprecated. 
Introduced new function: rte_eth_xstats_get_id_by_name to retrieve
xstats ids by its names.
Extended functionality of proc_info application:
--xstats-name NAME: to display single xstat value by NAME
Updated test-pmd application to use new API.

v4 changes:
documentation change after API modification
fix xstats display for PMD without _by_ids() functions
fix ABI validator errors

v3 changes:
checkpatch fixes
removed malloc bug in ethdev
add new command to proc_info and IDs parsing
merged testpmd and proc_info patch with library patch
