Maybe ethtool registers have some info?

# ethtool -S eth0

After:

And if you enable the debugfs option there is more info
hidden there.

# mount -t debugfs debugfs /sys/kernel/debug
# cat /sys/kernel/debug/sky2/eth0

There is no sky2 directory, maybe I don't have enough debug options in my kernel config.
