From: Felix Riemann <felix.riemann@sma.de>

If the cable is disconnected the PHY seems to toggle between MDI and
MDI-X modes. With the MDI crossover status interrupt active this causes
roughly 10 interrupts per second.

As the crossover status isn't checked by the driver, the interrupt can
be disabled to reduce the interrupt load.

Make sense, it is trying to find the RX pair...
