Getting NIC statistics using Ethtool.

[Paraneetharan Chandrasekaran]

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)?

Thanks in advance,
Paraneetharan C
