Sorry for pinging but could you review this rfc series? This is
not for the controller I mentioned a while ago, its for a
different one which I had a few free time to make a driver.
Though, the behavior and phy interface is similar, and the phy
driver used is the same also.

Best regards,
Jose Miguel Abreu
