[RFC 0/3] generic sw counters

[Stephen Hemminger]

This is my attempt to demonstrate:
  - generic counters for SW drivers, the example does af_packet and tap
    but same should be applied to af_xdp, virtio, etc.
  - counters are safe against 64 bit tearing on 32 bit platform
 
The naming and organization could be improved:
  - should this be in rte_ethdev?
  - better name for struct and vairables?
  - audit and handle errors better.

Stephen Hemminger (3):
  ethdev: add internal helper of SW driver statistics
  net/af_packet: use SW stats helper
  net/tap: use generic SW stats
