[net-next,v2,00/10] net: add and use dev_get_tstats64

Message

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.

v2:
- add patches for replacing ip_tunnel_get_stats64
  Requested additional migrations will come in a separate series.

Heiner Kallweit (10):
  net: core: add dev_get_tstats64 as a ndo_get_stats64 implementation
  net: dsa: use net core stats64 handling
  tun: switch to net core provided statistics counters
  ip6_tunnel: switch to dev_get_tstats64
  net: switch to dev_get_tstats64
  gtp: switch to dev_get_tstats64
  wireguard: switch to dev_get_tstats64
  vti: switch to dev_get_tstats64
  ipv4/ipv6: switch to dev_get_tstats64
  net: remove ip_tunnel_get_stats64
