Thanks. I'll complete the support as soon I'm back in the office. All
driver statistics are also available in the the proc system under
/proc/net/sk98lin/

Hi,
The following patch introduces the
ethtool support for the sk98lin
driver. Only 4 operations are supported
for now.
The patch is against vanilla 2.6.0.
As I dont have the hardware with me,
I could do only compilation test.
It compiles fine as inbuilt into
the kernel.
If you find this okay,
please consider it for the
inclusion in the mainline driver source.
(Enquiries were there for this feature,
Felix's mail to netdev.)
Regards,
KK.
