I wouldn't ask someone to do it and then tell them what language. Just suggest
to them what it needs to do instead.
The big question for me is: How do you propose to get the info out
of the driver and up to user-space?
Just in case it matters...while benchmarking my Linux ethtool patch to ath9k,
I found it took around 35us to make the ethtool ioctl call to get the
stats. This was on a dual-core Atom system.
Thanks,
Ben
