Don't worry, my English isn't perfect either;)

I send the following data over MDIO2(i don't know, why it doesn't work with MDIO1, but the port is addressed via bits 12 down to 8 of Address - you can find the details in the 'Embedded Peripherals IP User Guide' on p. 140):

x"81000104", x"0000C8E4"

x"81010104", x"000080E4"

x"81000004", x"0000C8E4"

Basically this is the flip_lanes command from the demo design tcl-skripts(http://www.altera.com/support/refdesigns/ip/interface/ref-10gbe-hardware-demo.html).

And thx for the hint with the DP83848VYB, I will take a look on it.
