[RFC v2 0/7] generic SW counters

[Stephen Hemminger <stephen@networkplumber.org>]

This is second attempt to demonstrate:
  - generic counters for SW drivers, the example does covers:
    af_packet, af_xdp, tap, ring but could be applied to virtio, etc.
  - counters are safe against 64 bit tearing on 32 bit platform
 
v2 - renamed and reorganized
   - put counters in eal, stats in ethdev internal functions
   - use offset to find stats in queue struct

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

Stephen Hemminger (7):
  eal: generic 64 bit counter
  ethdev: add internal helper of SW driver statistics
  net/af_packet: use SW stats helper
  net/tap: use generic SW stats
  net/pcap: use generic SW stats
  net/af_xdp: use generic SW stats
  net/ring: use generic SW stats
