From: Jacek Piasecki <jacekx.piase...@intel.com>
To achieve functionality of retrieving only specific statistics
given by application there are two new functions added:
eth_igb_xstats_get_by_ids() which retrieve
values of statistics specified by ids array
and eth_igb_xstats_get_names_by_ids() which retrieve
names of statistics specified by ids array.
