Hi all,

There maybe:
1. store software counters counted in software in stat_soft_last
2. store software counters counted in hardware in stat_hard_last
3. diff them after getting the fresh counters from hardware and software
4. wait for any "get statistic" request as done with hardware counters today
5. store the combination, taking "unseen packets" into account, 
    as the real netstat
6. goto 1.

What do you think?


Best Regards
