Hmmm. This sounds like a problem in the Linux network/PHY code then. Which
needs to get fixed there instead of changing something here in U-Boot. Please
think about situations where the ethernet driver is not called at all in U-
Boot (booting from NOR/NAND). With my changes to defer the ethernet probing to
the first usage.
One more comment below.
