<br><font size=2 face="sans-serif"> On my Cell blade this failed
on the latest build (be0646). Running with the changes to sungem_phy does
not allow the interfaces to ping anything. I went back to the original
and everything works again. All I did was change sungem_phy and force it
to be reloaded, let me know if I missed a step somewhere.</font>

While experimenting with a copper passthrough module in bladecenter I found
<br>
out that this needs autonegotiation enabled in order to work properly.<br>
This quick hack enables it with the sideeffect of breaking other bladecenter
<br>
switch configurations.<br>
If anyone has any suggestions or has experimented with the same configuration,
<br>
feel free to comment.<br>
<br>
This patch is not meant for inclusion into mainline.<br>
