Merge branch 'net-switch-further-drivers-to-core-functionality-for-handling-per-cpu-byte-packet-counters'

Heiner Kallweit says:

====================
net: switch further drivers to core functionality for handling per-cpu byte/packet counters

Switch further drivers to core functionality for handling per-cpu
byte/packet counters. All changes are compile-tested only.
====================
