+/**
+ * @brief Returns the Ethernet MAC address for a specified device.
+ *
+ * Applications may provide their own implementation of this function.  For
+ * example they can define their implementation in the same module which calls
+ * rtems_bsd_initialize().
+ *
+ * The default implementation returns
+ * { 0x0e, 0xb0, 0xba, 0x5e, 0xba, 0x11 + unit }.
+ *
+ * This is a workaround.  A better approach would be to use a device tree and a
+ * bus device similar to the FreeBSD SIMPLEBUS(4).
+ *
+ * @param[in] name The device name.
+ * @param[in] unit The device unit.
+ * @param[out] mac_addr The Ethernet MAC address.
