Hi Lorenzo,
Sorry for not noticing this earlier.
It seems to me that some of the stats above could
use standard stats, which is preferred.
Basically, my understanding is that one should:
1. Implement .ndo_get_stats64
(that seems relevant here)
2. As appropriate implement ethtool_stats non-extended stats operations
(perhaps not relevant here)
3. Then implement get_ethtool_stats for what is left over
...
