ixgbevf: provide 64 bit statistics
Compute statistics per ring using 64 bits, and provide network device stats in 64 bits. It should make this driver multiqueue operations faster (no more cache line ping pongs on netdev->stats structure) Use u64_stats_sync infrastructure so that its safe on 32bit arches as well.
