Good to know.

Any chance you can boot back to the old kernel (the one where is was
working) and run and ethtool -i eth0 on that one to see what version of
the driver was used there?  It's hard to know what may have changed
between the 2 versions of the driver since I don't know the starting
point.

It's also hard to know if this is fixed already since you aren't running
the latest upstream kernel.  Downloading, building, and testing the
latest from kernel.org would be a good way to know if this is already
fixed.
