/* Deactivate MDIO PHY auto polling. Some PHYs as the AR8030 have an
* interoperability problem with this auto polling mechanism because
* their status registers think that the link is in a different state
* than it actually is. For the AR8030 it has the BMSR_ESTATEN bit set
* as well as ESTATUS_1000_TFULL and ESTATUS_1000_XFULL. This makes the
* auto polling state machine consider the link being negotiated with
* 1Gbit/s. Since the PHY itself is a Fast Ethernet RMII PHY this leads
* to the switch port being completely dead (RX and TX are both not
* working).
* Also with various other PHY / port combinations (PHY11G GPHY, PHY22F
* GPHY, external RGMII PEF7071/7072) any traffic would stop. Sometimes
* it would work fine for a few minutes to hours and then stop, on
* other device it would no traffic could be sent or received at all.
* Testing shows that when PHY auto polling is disabled these problems
* go away.
