This API break is to allow changing the API of xstats given the conversation that was on-list, as discussed in this thread:

http://thread.gmane.org/gmane.comp.networking.dpdk.devel/31728/focus=31903

The issue we are going to fix is that currently PMDs copy strings when retrieving statistics, which causes unnecessary overhead. The implementation is not decided yet, but using an int->value mapping seems logical.

The rte_eth_xstats struct size may be modified, and the API to retrieve statistics will be modified.
