      Interrupts are broken on some GPY2xx PHYs in that they keep the
      interrupt line asserted even after the interrupt status register is
      cleared. Thus it is blocking the interrupt line which is usually bad
      for shared lines. By default interrupts are disabled for this PHY and
      polling mode is used. If one can live with the consequences, this
      property can be used to enable interrupt handling.

      Affected PHYs (as far as known) are GPY215B and GPY215C.
