[dpdk-dev] [PATCH] ether: fix incorrect stats query for lowest xstat id

Applied, thanks

It looks like the stats functions are the most reworked and fixed.
It is a no-end story. According to git statistics, it is probably
the most complicate code of DPDK :)
I am thinking about being more conservative and do not accept any
new change in these rocket science functions ;)
