That's hard for me to judge since for me it's never worked.  Anyway, as
reported in an earlier post to the list, the patch you sent seems to send
the PHY into 1 Gbps mode.  Realtek's driver made the interface come alive
but only at 100 Mbps.  So in that respect the patch seems good.

After sending the post last night I tested the behaviour across a hard power
cycle.  In short, the interface seems to come up in 100 Mbps mode on power
up, and then switches to 1 Gbps once the patched Linux 8169 driver loads. 
So it seems Realtek's driver has a side effect of storing some kind of
default mode into the device.  The patch however does seem to allow Linux to
gain control over this and set things up to its liking.

As I mentioned, if there are other tests you want me to do just drop me a
line.
