Somewhere in the above space, there should have been a COMPLETE dmesg
output from your system, but apparently the e-mail gremlins ate it.

Given that I actually tested an RTL8111B/RTL8168B sample card and it
worked fine with this code, RIGHT BEFORE I CHECKED IT IN, I'm forced
to conclude that this problem is one of your own devising. I'm sure
there's a big fat clue to the problem in the dmesg output that you
didn't send.

You didn't give me enough information to answer this question. Since
you declined to state EXACTLY what you did, I can't tell you where
you went wrong.
