Subject: [PATCH net-next 0/5] net: add and use dev_get_tstats64

It's a frequent pattern to use netdev->stats for the less frequently
accessed counters and per-cpu counters for the frequently accessed
counters (rx/tx bytes/packets). Add a default ndo_get_stats64()
implementation for this use case. Subsequently switch more drivers
to use this pattern.

Heiner Kallweit (5):
  net: core: add dev_get_tstats64 as a ndo_get_stats64 implementation
  net: make ip_tunnel_get_stats64 an alias for dev_get_tstats64
  ip6_tunnel: use ip_tunnel_get_stats64 as ndo_get_stats64 callback
  net: dsa: use net core stats64 handling
  tun: switch to net core provided statistics counters
