Yeah, they should implement. But, its upto the person who wrote the driver of Atheros(In generally, for Intel/Broadcom, they provides the features of stats information through the function pointer "get_ethtool_stats"). >If not, how can I know what format used by the driver I am working on ( I am working on Atheros driver)? Verify your application first on Intel/Broadcom driver if its works fine, then verify it on your Atheros driver. If your Atheros driver doesn't provide these feature, then do the similar enhancement in your Atheros driver by cross-checking with Intel/Broadcom drivers.
