The statistics available through ethtool are entirely driver-dependent.
There is a small set of standard statistics which are shown in
/proc/net/dev and under /sys/class/net/<name>/statistics/.

All pause frames should be dropped, either by the hardware or the driver.
So it's not unexpected that these are equal.
It might be interesting to see what happens if you disable pause frame
handling with this command:
ethtool -A eth0 autoneg off rx off tx off

I can't see any major changes in the forcedeth driver since 2.6.30.

We will shortly update the official kernel packages to incorporate this
release, so you could just wait a day or two and update. However I'm not
aware of any changes in 2.6.32.10 that would fix this sort of bug.
