/**
* @brief PHY detection timeout.
* @details Timeout, in milliseconds, for PHY address detection, if a PHY
* is not detected within the timeout then the driver halts during
* initialization. This setting applies only if the PHY address is
* not explicitly set in the board header file using
* @p BOARD_PHY_ADDRESS. A zero value disables the timeout and a
* single search path is performed.
* @details Timeout for PHY address detection, the scan for a PHY is performed
* the specified number of times before invoking the failure handler.
