Hi All,
I am writing an user space application which gets the statistics from
the NIC drivers. To do this, I am using Ethtool ioctl with Ioctl
command SIOCETHTOOL and with ethtool command ETHTOOL_GSTATS along with
the address of struct ethtool_stats variable. My question is:

What would be the format of the statistics copied from the kernel
space (to the address pointed by the data field of struct
ethtool_stats) ?

Do all the drivers implement the same data format when they copy the
statistics to user space in response to this Ethtool ioctl?

If not, how can I know what format used by the driver I am working on
( I am working on  Atheros driver)?

You can get driver info from ethtool's get_drvinfo option.
Hence you can put a check in your application for a particular(like Intel and Broadcom ) driver.

Thanks,

Thanks in advance,
