EDK10.1 and emaclite

[John Linn]

Hi Georg,

There is no way to configure the PHY using the EMAC lite as that's part
of what makes it "lite".  

So the PHY on the board has to be configured correctly by strapping it
on the board.

Maybe you can include other PHY drivers to do this as I'm not sure about
that.

Thanks,
John
