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.

ethdev: add internal helper of SW driver statistics
net/af_packet: use SW stats helper
net/tap: use generic SW stats
