/**
* @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.
