netxen driver has implemented netxen_nic_get_ethtool_stats() interface,
but it doesn't collect stats.rxdropped in driver, so we will get
different rx_dropped statistic information while using ifconfig and ethtool.
hi,
Regarding the r8169 chip, there is no other data fields exported to
user via ethtool
except for those dumped from hardware statistic counters in 8169 driver.
But for Intel 82598 NIC and its driver ixgbe, it exports not only
those fields dumped from hardware statistic counters, like:

I think ethtool stats are adapter specific. Driver does not maintain
rx_dropped stats and we also don't get it from adapter. I am not
sure if ethtool stats should match
