Hi,
Thank you. But my intention is getting statistics in user space through ethtool. The ethtool_interfaces like get_ethtool_stats, get_drvinfo etc are in kernel space. If call the Ioctl with ETHTOOL_GSTATS, I dont know how to parse the returned data. What is the format of the returned statistics? is there any format which all the drivers support?
Thank you

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,
