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
