Merge branch 'net_device_stats'

Tobias Klauser says:

====================
Use net_device_stats from struct net_device

Along the lines of previous patches, switch (almost) all remaining net
drivers to use net_device_stats from net_device instead of including a
copy of it in their netdev_priv struct.
====================
