That I find hard to believe. You were seeing a combination of "MII status
changed" and "Abort 0208, frame dropped.". That's because the driver makes
two mistakes: It treats 0200 as a link change (first message), and it
thinks 0008 indicates excessive collisions (second message).

In fact, 0008 means "transmission error", and 0200 specifies a buffer
underrun. The patch fixes that (lines 204, 213). If you are seeing the
_same_ errors my guess is you're still running the old driver. Check the
log at debug=3.

It's masking another bug that's waiting to hit you <g>.
