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

http://thread.gmane.org/gmane.comp.networking.dpdk.devel/31728/focus=3D3190=
3

The issue we are going to fix is that currently PMDs copy strings when retr=
ieving 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 sta=
tistics will be modified.
