+/****************************************************************************
+ * Function: sam_ioctl
+ *
+ * Description:
+ *  Handles driver ioctl calls:
+ *
+ *  SIOCMIINOTIFY - Set up to received notifications from PHY interrupting
+ *    events.
+ *
+ *  SIOCGMIIPHY, SIOCGMIIREG, and SIOCSMIIREG:
+ *    Executes the SIOCxMIIxxx command and responds using the request struct
+ *    that must be provided as its 2nd parameter.
+ *
+ *    When called with SIOCGMIIPHY it will get the PHY address for the device
+ *    and write it to the req->phy_id field of the request struct.
+ *
+ *    When called with SIOCGMIIREG it will read a register of the PHY that is
+ *    specified using the req->reg_no struct field and then write its output
+ *    to the req->val_out field.
+ *
+ *    When called with SIOCSMIIREG it will write to a register of the PHY that
+ *    is specified using the req->reg_no struct field and use req->val_in as
+ *    its input.
+ *
+ * Parameters:
+ *   dev - Ethernet device structure
+ *   cmd - SIOCxMIIxxx command code
+ *   arg - Request structure also used to return values
+ *
+ * Returned Value: Negated errno on failure.
+ *
+ * Assumptions:
