- Using the NIC data structure information, read the EEPROM to get the MAC address and then allocate space
- for a new devicepath (**DevPtr) which will contain the original device path the NIC was found on (*BaseDevPtr)
- and an added MAC node.
-
-Arguments:
-
- DevPtr - Pointer which will point to the newly created device path with the MAC node attached.
-
- BaseDevPtr - Pointer to the device path which the UNDI device driver is latching on to.
-
- AdapterInfo - Pointer to the NIC data structure information which the UNDI driver is layering on..
-
-Returns:
-
- EFI_SUCCESS - A MAC address was successfully appended to the Base Device Path.
-
- other - Not enough resources available to create new Device Path node.
