RE: 83xx, ucc_geth, kernel 2.6.23, IP-Config: No network devices

Joch,

Thanks, apparently I had a conditional that was not matching up around that
call. So now that I 'am' calling the of_platform_bus_probe(). I can see all
the probe functions getting called.  Thank you very much.

Next question, I can see that 'quick' mods I have made to the Marvell driver
are indeed matching up with the device ID that the Freescale MII device is
pulling back from my 'National' part. <I'll make a real phy driver once I
get this working>. I.e. I can see the phy_probe get called when this Id is
registered.  You can see the extra debug messages above the National DP83865
device registration, and the probe returns 0 for success I assume. <err =
0>.

I am still getting the "IP-Config: No network devices" error before the NFS
boot tries to take place.
