ixgbe: fix stats handling
Current ixgbe stats have following problems :
- Not 64 bit safe (on 32bit arches)
- Not safe in ixgbe_clean_rx_irq() :
All cpus dirty a common location (netdev->stats.rx_bytes &
netdev->stats.rx_packets) without proper synchronization.
This slow down a bit multiqueue operations, and possibly miss some
updates.
Fixes :
Implement ndo_get_stats64() method to provide accurate 64bit rx|tx
bytes/packets counters, using 64bit safe infrastructure.
ixgbe_get_ethtool_stats() also use this infrastructure to provide 64bit
safe counters.
