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.
v3:
- add atomic_long_t member rx_frame_errors in patch 3 for making
counter updates atomic
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: use ip_tunnel_get_stats64 as ndo_get_stats64 callback
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
