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 ifconfig stats as ifconfig also
adds net core stats to adapter stats.

If ethtool stats should report same values as ifconfig stats then
we may also need to fix tx_dropped statistics.

Thanks,
Rajesh
