Ah finally. I tried to contact you several times before. 
(RFC back in May)

Sven, I've seen you did quite a bit of work on the OM5P-AN
with the same F1E-PHY. I went through the code from Atheros'
original driver SDK v17 (which was part of the GPL source
for the mynet). Apart from tx delay handling, everything
else matches perfectly, so the tx/rx delay code should be
enabled by default for this chip on all platforms without
needing any platform data overwrites.

I'm interested to hear from any other devices which have 
a AT803x. Also, please let me know where to get the GPL
tars for the devices.
